Hi group,
I am sitting here trying to determine what the subtle differences are
between the various methods of configuring redistribution when there are
multiple redistribution points, in this case it is EIGRP<->OSPF.
I like to typically use the route tags to do my filtering, but I find
that this does not work if there is a backup scenario, and the protocol
domain becomes partitioned. It seems easy and straight forward.
The alternate method I have read about (probably on the list) is
altering Admin Distance for the routes redistributing at the protocol
boundary. I found this works for the partitioned domain problem. I
believe by adding an external distance to OSPF higher than EIGRP
external, it can ignore routes that would cause a route loop. I am
still pondering this however. :)
Is there any good doc to read to understand the subtle art of
redistribution and other methods of doing it, and perhaps situations
when to apply one versus another?
Just when I thought I had a concept down...it scurries away. :)
Jason
