Hi Experts Could you please help regarding the below scenario.
In the hub and spoke topology shown in the uploaded diagram, S2 which is running OSPF is advertising the external route 22.214.171.124/24 and the summary 192.168.4.4/32.
No changes in the domain-id value between R5 and R1 in order to keep the summary route as is. On R1 the routes are imported in the Spoke vrf which imports all spokes routes and exports null. The OSPF under this vrf is this configured with domain-vpn tag 0 to allow the hub CE which receives the 2 routes to redistribute the external route back to the hub vrf on R1.
The hub vrf is responsible of advertising the routes to the rest of spoke sites.
The question is why unlike the external route, the summary is not showing on the hub vrf table although it is present in hub database and how caw overcome this issue ?
