In this section for injecting a default route you only do it if
your route-map matches the networks in question. Like for instance as
long as I have a route to 192.10.1.0/24 advertise the default route.
Well what if I wanted to advertise the default route if I lost a
route in my route table ? Like for instance lets say if I lost my
connection to BB2 would I use
router ospf 1
default-information originate always route-map CONDITION
ip prefix-list BB2 seq 5 permit 192.10.1.0/24
ip prefix-list BB3 seq 5 permit 204.12.1.0/24
route-map CONDITION deny 10
match ip address prefix-list BB2
rute-map CONDITION deny 20
match ip address prefix-list BB3
I think with this I would only advertise the default route if I
lose either route in my route table is this correct ?
Also with this solution would I only advertise the default route if
I lose both connections at the same time ?
router ospf 1
default-information originate always route-map CONDITION
ip prefix-list BB2 seq 5 permit 192.10.1.0/24
ip prefix-list BB2 seq 5 permit 204.12.1.0/24
route-map CONDITION deny 10
match ip address prefix-list BB2
