Hello All,
We currently have an OSPF backbone of 70 routers with 1000 OSPF routes. We’re trying to add an additional stub router as an NSAA to our network. (We only want that router to receive a default route)
Between the main router and the NSAA router, we have “Redistribute default route” set to type 1 on the instance specific to the NSAA router.
As intended, the NSAA router receives only a default route, but after about an hour, the route disappears. OSPF state is still @ Full.
When we reboot the router or make a change to OSPF (which causes the state to go down then to full), the default route is once again present, but after an hour or so, the default route disappears once again.
Any thoughts? We’ve tried also the network type as broadcast, PTMP, PTP.
Configs on the border router:
/routing ospf instance
set [ find default=yes ] redistribute-connected=as-type-1 redistribute-other-ospf=as-type-1 router-id=x.x.x.39
add distribute-default=always-as-type-2 in-filter=ospf-in name=WAN out-filter=ospf-out router-id=x.x.x.39
/routing ospf area
add area-id=0.0.73.0 default-cost=1 inject-summary-lsas=no instance=WAN name=CUSTOMERNSAA translator-role=\
translate-never type=nssa
/routing ospf network
add area=CUSTOMERNSAA network=172.24.10.108/30
Configs on the NSAA Client Router
