Hi all,
I have to deploy MPLS based on OSPF as IGP, the backbone is build on Cisco
12000 GSRs (12008,12012 12016). I heard that MPLS over OSPF on GSR can
cause some problems (ISIS is prefered as IGP ...) but I don't have details
about these problems. Does anybody experienced bugs with this kind
Hi all,
I have some questions about IGRP :
- In an update, IGRP distinguish Subnets, AS Networks and outside-AS
networks, when I take some traces, I can see that there's the number of each

if the routing entry is Subnet,
692 was the pass for me, I passed it last monday with 896

So triggered updates are not generated when using redistribution (It worked
fine with RIP, so I supposed that it should work with IGRP, but no).

A serial link, is not a shared media.
Serial link is used for point to point connection = no collision
U can have collision if Tx is connected on Tx on the other side of the
cable, but if the cable and interfaces (X21, V24 ...) are good, there's no
collision.

I agree with you.
Serial link is not always full duplex. It depends of the relation between

A couple of suggestions:

Hi all,
I'm trying to find a regexp to match AS PATH including AS200 only, but AS200
can be contained more than one time (AS PATH prepending).
Example :
200 - Match
200 200 - Match
200 200 200 - Match
200 200 200 300 - Don't Match
I tried to use this regexp : ^(200)+$ but it doesn't work, why ?
on the egress interface, the entry
disappears and no more entry are cached for this interface when packet come.
For me, issuing the command no ip route-cache on an interface, disables
caching for this interface.
