Figure 4-11 IS-IS Multi-Instance Configuration Example

Configuration Thought
1. Establish neighbor relationship on vlan10 of S1 and vlan10 of S2 in Instance 100.
2. Establish neighbor relationship on vlan20 of S1 and vlan20 of S2 in Instance 200.
3. Redistribute direct-connected routes in the instances of S1. Check whether load
sharing is performed through different instances on S2. (Load sharing cannot be
performed, as the route with a smaller instance number of the same prefix has a
higher priority.)
Configuration Process
Configuration on S1:
S1(config)#router isis 100
S1(config-isis-100)#system-id 1111.0100.0000
S1(config-isis-100)#area 10
S1(config-isis-100)#redistribute connected
S1(config-isis-100)#interface vlan10
S1(config-isis-100-if-vlan10)#ip router isis
S1(config-isis-100-if-vlan10)#exit
S1(config-isis-100)#exit
S1(config)#router isis 200
S1(config-isis-200)#system-id 1111.0200.0000
S1(config-isis-200)#area 10
S1(config-isis-200)#redistribute connected
S1(config-isis-200)#interface vlan20
S1(config-isis-200-if-vlan20)#ip router isis
S1(config-isis-200-if-vlan20)#exit
S1(config-isis-200)#exit
Configuration on S2:
S2(config)#router isis 100
S2(config-isis-100)#system-id 2222.0100.0000
S2(config-isis-100)#area 10
S2(config-isis-100)#interface
S2(config-isis-100-if-vlan10)#ip router isis
S2(config-isis-100-if-vlan10)#exit
S2(config-isis-100)#exit
S2(config)#router isis 200
S2(config-isis-200)#system-id 2222.0200.0000
