I'm trying to apply a table-map for an OSPFv2 issue which would cause loops
I've got a couple of 7Ks connected to two OSPF domains, interconnected on both domains, and the redistribution from domain 1 to domain 2 issues a tag.
When I try to run a table-map with a route-map deny statement to match the tag issued it still lets the routes into the routing table.
(To clarify: N7kA might originate a in domain 1 route and N7kB redistributes it into domain 2 which passes it back to N7kA via domain 2, and having a smaller AD creates a loop)
I'm trying to get no routes from OSPF1 to show in the RIB via the OSPF2 process but still want to pass them to the rest of the domain so RIB filtering seems the way.
Am I being stupid in that the table-map won't work because the routes exist from another process so they will still be added with their best AD or something? I can't find a lot of information on table-maps only that they seem to replace distribution-lists for ospf?
I used prefix-lists to get around this and administrative distance changes but it lookts like the reason the table-map didn't work is that I'd hit a bug. Updating should cover this in case it affects someone else.
Table-map with keyword 'filter' along with route-map deny incorrectly updates the RIB table Whenver a table-map with filter along with route-map deny is configured, the routes matching the route-map should be discarded from downloading into RIB table. But doing clear isis adjacency *, clear ip/ipv6 route * downloads the routes into RIB table with default admin distance. Routes matching route-map with deny should not downloaded into RIB table when negative cases are executed.
