=Конфигуриране на S1=
 +
Първоначално е необходимо да се провери и/или активира SDM Template Lanbase-routing. За целта се използва командата '''sdm prefer lanbase-routing''':
 +
 +
<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap;white-space: -pre-wrap;white-space: -o-pre-wrap; word-wrap: break-word">
 +
Switch#conf t
 +
Enter configuration commands, one per line.  End with CNTL/Z.
 +
Switch(config)#
 +
Switch(config)#sdm prefer lanbase-routing
 +
Changes to the running SDM preferences have been stored, but cannot take effect
 +
until the next reload.
 +
Use 'show sdm prefer' to see what SDM preference is currently active.
 +
Switch(config)#
 +
Switch(config)#do reload
 +
</pre>
 +
 +
Проверката на активния в момента SDM Template се извървшва с '''show sdm prefer''':
 +
<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap;white-space: -pre-wrap;white-space: -o-pre-wrap; word-wrap: break-word">
 +
Switch#show sdm prefer
 +
The current template is "lanbase-routing" template.
 +
The selected template optimizes the resources in
 +
the switch to support this level of features for
 +
0 routed interfaces and 255 VLANs.
 +
 +
  number of unicast mac addresses:                  4K
 +
  number of IPv4 IGMP groups + multicast routes:    0.25K
 +
  number of IPv4 unicast routes:                    4.25K
 +
    number of directly-connected IPv4 hosts:        4K
 +
    number of indirect IPv4 routes:                256
 +
  number of IPv6 multicast groups:                  0.375k
 +
  number of IPv6 unicast routes:                    1.25K
 +
    number of directly-connected IPv6 addresses:    0.75K
 +
    number of indirect IPv6 unicast routes:        448
 +
  number of IPv4 policy based routing aces:        0
 +
  number of IPv4/MAC qos aces:                      0.125k
 +
  number of IPv4/MAC security aces:                0.375k

  number of IPv6 policy based routing aces:        0
 +
  number of IPv6 qos aces:                          0.375k
 +
  number of IPv6 security aces:                    127

 +
Спрямо примерната топология на S1 следва да се конфигурират VLAN, Trunk, SVI и маршрутизирането на трафика:
 +
 +
<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap;white-space: -pre-wrap;white-space: -o-pre-wrap; word-wrap: break-word">
 +
enable
 +
conf t
 +
hostname S1
 +
 +
vlan 10
 +
vlan 20
 +
vlan 30
 +
vlan 99
 +
exit
 +
 +
interface range gi0/1-2
 +
switchport mode trunk
 +
switchport trunk native vlan 99
 +
 +
interface range fa0/1-8
 +

 +
switchport access vlan 10
 +
interface range fa0/9-16
 +
switchport mode access
 +
switchport access vlan 20
 +
interface range fa0/17-24
 +
switchport mode access
 +
switchport access vlan 30
 +
exit
 +
 +
interface vlan 10
 +
ip address 10.10.0.1 255.255.0.0
 +
interface vlan 20
 +
ip address 10.20.0.1 255.255.0.0
 +
interface vlan 30
 +
ip address 10.30.0.1 255.255.0.0
 +
 +
ip routing
 +
 +
end
 +
</pre>
 +
 +
=Проверка на интерфейсите=
 +
За да се проверят IPv4 адресите на SVI може да се използва командата '''show ip interface brief''':
 +
 +
<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap;white-space: -pre-wrap;white-space: -o-pre-wrap; word-wrap: break-word">
 +
S1#show ip interface brief
 +

 +

 +
Vlan20                10.20.0.1      YES manual up                    up
 +
Vlan30                10.30.0.1      YES manual up                    up
 +
...
 +
</pre>
 +
 +
=Проверка на маршрутизиращата таблица=
 +
Аналогично на маршрутизаторите за да се провери съдържанието на IPv4 маршрутизиращата таблица може да се използва командата '''show ip route''':
 +
<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap;white-space: -pre-wrap;white-space: -o-pre-wrap; word-wrap: break-word">
 +
show ip route
 +
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
 +
      D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
 +
      N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
 +
      E1 - OSPF external type 1, E2 - OSPF external type 2
 +
      i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
 +
      ia - IS-IS inter area, * - candidate default, U - per-user static route
 +
      o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
 +
      + - replicated route, % - next hop override
 +
 +
Gateway of last resort is not set
 +
 +
      10.0.0.0/8 is variably subnetted, 6 subnets, 2 masks
 +
C        10.10.0.0/16 is directly connected, Vlan10
 +
L        10.10.0.1/32 is directly connected, Vlan10
 +
C        10.20.0.0/16 is directly connected, Vlan20
 +
L        10.20.0.1/32 is directly connected, Vlan20
 +
C        10.30.0.0/16 is directly connected, Vlan30
 +
L        10.30.0.1/32 is directly connected, Vlan30
 +
</pre>
 +
 +
=Маршрутизиране на трафика чрез статични пътища=
 +
==Добаване на път по подразбиране==
 +
Чрез SDM Template Lanbaserouting комутаторът Catalyst 2960 поддържа '''до 16 статични пътя'''.
 +
Добаването на път по подразбиране е аналогично на маршрутизатора и е чрез командата '''ip route 0.0.0.0 0.0.0.0''' ''next-hop'':
 +
<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap;white-space: -pre-wrap;white-space: -o-pre-wrap; word-wrap: break-word">
 +
S1(config)#ip route 0.0.0.0 0.0.0.0 192.168.0.1
 +
</pre>
 +
 +
==Добавяне на статични пътища към отдалечени мрежи==
 +
Отново аналогично на конфигуриането на маршрутизатори за да се опишат статичните пътища към отдалеченик мрежи се използва командата '''ip route''' ''мрежови адрес'' ''маска'' ''next-hop''.
 +
 +
=Конфигурация на S1, S2 и S3=
 +

Примерна топология (IPv4)

Lanbase Routing Topology.PNG

В примера е разгледана конфигурацията на S1. Устройства S2 и S3 се използват като стандартни L2 комутатори, с конфигурирани VLAN и Trunk,

SDM Templates

С помощта на SDM Templates е възможно при комутаторите на Cisco Systems да се оптимизират или активират дадени услуги. По подразбиране при IOS 15 Catalyst 2960 не поддържа маршрутизиране на трафика чрез статични пътища, но след активиране на sdm prefer lanbase-routing тази функционалност се активира.

Допълнителна информация за SDM Templates при Catalyst 2960 можете да намерите на адрес: Configuring SDM Templates

Конфигуриране на S1

Първоначално е необходимо да се провери и/или активира SDM Template Lanbase-routing. За целта се използва командата sdm prefer lanbase-routing: 

Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#
Switch(config)#sdm prefer lanbase-routing
Changes to the running SDM preferences have been stored, but cannot take effect
until the next reload.
Use 'show sdm prefer' to see what SDM preference is currently active.
Switch(config)#
Switch(config)#do reload

Проверката на активния в момента SDM Template се извървшва с show sdm prefer: 

Switch#show sdm prefer
 The current template is "lanbase-routing" template.
 The selected template optimizes the resources in
 the switch to support this level of features for
 0 routed interfaces and 255 VLANs.

Спрямо примерната топология на S1 следва да се конфигурират VLAN, Trunk, SVI и маршрутизирането на трафика: 

enable
conf t
hostname S1

vlan 10
vlan 20
vlan 30
vlan 99
exit

interface range gi0/1-2
switchport mode trunk
switchport trunk native vlan 99

interface range fa0/1-8
switchport mode access
switchport access vlan 10
interface range fa0/9-16
switchport mode access
switchport access vlan 20
interface range fa0/17-24
switchport mode access
switchport access vlan 30
exit

interface vlan 10
ip address 10.10.0.1 255.255.0.0
interface vlan 20
ip address 10.20.0.1 255.255.0.0
interface vlan 30
ip address 10.30.0.1 255.255.0.0

ip routing

end

Проверка на интерфейсите

За да се проверят IPv4 адресите на SVI може да се използва командата show ip interface brief: 

S1#show ip interface brief
Interface              IP-Address      OK? Method Status                Protocol
Vlan1                  unassigned      YES unset  administratively down down
Vlan10                 10.10.0.1       YES manual up                    up
Vlan20                 10.20.0.1       YES manual up                    up
Vlan30                 10.30.0.1       YES manual up                    up
...

Проверка на маршрутизиращата таблица

Аналогично на маршрутизаторите за да се провери съдържанието на IPv4 маршрутизиращата таблица може да се използва командата show ip route: 

show ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
       + - replicated route, % - next hop override

Gateway of last resort is not set

      10.0.0.0/8 is variably subnetted, 6 subnets, 2 masks
C        10.10.0.0/16 is directly connected, Vlan10
L        10.10.0.1/32 is directly connected, Vlan10
C        10.20.0.0/16 is directly connected, Vlan20
L        10.20.0.1/32 is directly connected, Vlan20
C        10.30.0.0/16 is directly connected, Vlan30
L        10.30.0.1/32 is directly connected, Vlan30

Маршрутизиране на трафика чрез статични пътища

Добаване на път по подразбиране

Чрез SDM Template Lanbaserouting комутаторът Catalyst 2960 поддържа до 16 статични пътя. Добаването на път по подразбиране е аналогично на маршрутизатора и е чрез командата ip route 0.0.0.0 0.0.0.0 next-hop: 

S1(config)#ip route 0.0.0.0 0.0.0.0 192.168.0.1

Добавяне на статични пътища към отдалечени мрежи

Отново аналогично на конфигуриането на маршрутизатори за да се опишат статичните пътища към отдалеченик мрежи се използва командата ip route мрежови адрес маска next-hop.
