Advertise ospf into omp

[masohle1]

I configured OSPF on my service side in order to have reachability from the cEdge to my end-host in the LAN. This reachability is working well. However the LAN subnet is not being learned by OMP and thus not being advertised to other sites. So, I had to configure a RIP in my LAN subnet in order for OMP to learn it and advertise it.

I need to advertise OSPF not OSPF external

Thanks

Hello @masohle1 

OMP automatically redistributes the following types of routes:

• Connected
• Static
• OSPF Intra-Area
• OSPF Inter-Area

The reason your OSPF routes are not being advertised by OMP is that OMP automatically redistributes only OSPF intra-area and inter-area routes, not external routes unless explicitly configured. While the reachability between your cEdge and the LAN works, OMP requires explicit configuration to redistribute OSPF routes. The workaround you used with RIP works because RIP routes are treated as connected or static, which OMP automatically learns and advertises.

So, you need to configure OSPF redistribution into OMP on the cEdge.

Check:
