Nigel,
Yes..the route does not exist on R1 because redistribution is not working on
R3. The goal would be for R1 to learn about 151.1.12.0/28 via OSPF ( becuase
of redistribution on R3 )
151.1.12.0/28 is directly connected (multipoint) network on R3...but is also
advertised in eigrp and ospf. The routes 151.1.12.2/32 and 151.1.12.5/32
show up in the routing table because of the default behavior of OSPF on
multipoint links.....hence the /32.
I am confused as to why the network 151.1.12.0/28 is not showing up in the
ospf database...you would think this would be the case since it is
redistributed into ospf from eigrp.
* 151.1.12.0/28 is directly connected on R3
* 151.1.12.0/28 is advertised in EIGRP
* EIGRP is redistributed into OSPF
* R3 will not show 151.1.12.0/28 as EIGRP or OSPF route because it is a
directly connected route.
* R3 should show routes from router-id 2.2.2.2 in it's ospf database..but it
does not.
* R1 should see 151.1.12.0/28 as OSPF external route...but it does not.
* R1 should have routes from router-id 1.1.1.1 in it's ospf database but it
does not.
Any other ideas?
Thanks,
Dain
