Conditional default route advertisement in ISIS (IOS XR)
I am doing conditional default route advertisement in ISIS on IOS XR as follows:
route-policy PL-DEFAULT-ROUTE-CONDITION if rib-has-route in (172.16.10.1/32, 172.16.10.2/32) then set level level-1 endif end-policy ! router isis core address-family ipv4 unicast default-information originate route-policy PL-DEFAULT-ROUTE-CONDITION
It is working like a charm.
Now, I would like to change my condition, and instead of looking for specific /32 routes, I would like to look for routes with some community attached, so I change my RP to following:
route-policy PL-DEFAULT-ROUTE-CONDITION if community matches-any (65000:1) then set level level-1 endif end-policy
but with that I get commit error:
RP/0/0/CPU0:02-ABR2(config)#show configuration failed Tue Jul 8 18:51:27.895 UTC !! SEMANTIC ERRORS: This configuration was rejected by !! the system due to semantic errors. The individual !! errors with each failed configuration command can be !! found below.
