Hi All,
On a router, I am redistributing rip to ospf.I have a default-route learnt
via RIP installed in the routing table.
While redistributing,this default route is not picked automatically and sent
into the OSPF domain.I had to use default-information originate to pass on
this default route into my ospf domain.
Is this an expected behavior?
Configs :
router ospf 1
router-id 150.1.7.7
log-adjacency-changes
redistribute rip subnets
network 163.1.0.1 0.0.0.0 area 0

redistribute ospf 1 metric 1

no passive-interface Vlan57
network 150.1.0.0
network 163.1.0.0
no auto-summary
