Isis Hierarchical Configuration: Example - Cisco ASR 9000 Series User Configuration Manual

ISIS Hierarchical Configuration: Example

!
RP/0/RSP0/CPU0:router# show running interface gigabitEthernet 0/0/0/38
interface GigabitEthernet0/0/0/38
!
RP/0/RSP0/CPU0:router# show running inheritance interface gigabitEthernet 0/0/0/38
interface GigabitEthernet0/0/0/38
!
4 Use a traffic generator to verify that the traffic pattern for interface GigabitEthernet0/0/0/39 gets acted on
by the access list in the local configuration (smany) and not according to the inherited referenced access
list (adem).
ISIS Hierarchical Configuration: Example
This example illustrates inheritance and priority handling with two ISIS groups using an ISIS configuration.
1 Configure the local ISIS configuration:
RP/0/RSP0/CPU0:router# show running router isis
