ISP1 has Two connection -> BGP default-information origiate along with other
routes
ISP2 has one connection -> BGP default-information origiate along with other
routes
I want to redistribute BGP default route into ospf. I tried "redistribute
bgp as# subnet route-map DEFAULT->OSPF". This did not worked. Then searched
on univercd ospf session, It says ASBR will not insert default route.
"default-information originate" will force to insert default route. However,
I wanted to updated default route information when BGP default route
information changed.
So I used default-information originate route-map DEFAULT->OSPF.
router ospf 200
router-id 150.1.1.1
log-adjacency-changes
redistribute static subnets
network 10.1.0.0 0.0.255.255 area 1
network 150.1.1.1 0.0.0.0 area 0
network 155.1.12.1 0.0.0.0 area 0
network 155.1.13.1 0.0.0.0 area 1
network 155.1.146.1 0.0.0.0 area 0
default-information originate route-map DEFAULT->OSPF
route-map DEFAULT->OSPF permit 10
match ip address prefix-list DEFAULT->ROUTE
!
ip prefix-list DEFAULT->ROUTE seq 5 permit 0.0.0.0/0
Then OPSF network has default routes and updated when BGP default route
changed.
This is what I wanted but I am wondering there are any better way doing
this.
