Hi Aaron,
I may be confused, but is there any reason you are trying to setup a virtual
link between a loopback interface and a serial interface. Why don't you set
it up where each loopback is pointing to each otheras follows:
On r3
interface Loopback1
ip address 10.44.2.1 255.255.255.252
etc
router ospf 1
network 10.44.2.1 0.0.0.0 area 3
area 3 virtual-link 10.34.1.1 (assume this is your r4 loopback1)
On r4
interface Loopback1
ip address 10.34.1.1 255.255.255.252
etc
router ospf 1
network 10.34.1.1 0.0.0.0 area 3
area 3 virtual-link 10.44.2.1
After you have it all set up, check it with the command 'sh ip ospf
virtual-links'
I have not set this up yet, but I think it is reasonable. If I remember
correctly, by default, the
ospf outer id is the address assigned to the first loopback interface or if
the loopback is not
defined, the next highest numbered ip address on the router. So in your
case, if the router id
is assigned by use of the loopback interface, it will always exists as long
as the router is reachable via a physical interface (eg. serial) the virtual
link will work.
I ask some of the ospf gurus on the list to clarify/expand on this so we all
come away with a
good understanding..dj
