Customer need to advertise one subnet from HQ AR router to connected Juniper FW, connection as below
Subnet need to be advertised 10.41.70.0 0.0.0.255 , which is orginated from DR AR3200 on the right side
DR AR3200 >> HQ AR3200 >> Juniper FW connected with BGP
After check the ospf routing table on HQ AR, we found that the route 10.41.70.0/24 is under ospf 2015 but not under ospf 2016, so when import-route ospf 2016 to bgp, this route can’t be sent to BGP routing table.
There is a way of solving this problem:
Import-route ospf 2015 to BGP, and add route-policy . (example: FSE want to 10.41.70.0/24 advertise to FW)
The configuration is below:
acl number 2002
rule permit source 10.41.70.0 0.0.0.255
route-policy ospftobgp-2 permit node 10
if-match acl 2002
import-route ospf 2015 route-policy ospftobgp-2
Please check this configuration.
