Hi list,
In an enterprise network I have a core of 4900Ms with a few ASR1ks hanging off
to handle upstream connectivity. As an example:
Upstream1 - [ASR1k]--[4900M]--[4900M]--[ASR1k] - Upstream2
| |
| |
Servers Workstations, etc
The ASRs and 4900Ms are running BGP and ISIS with full tables on the ASRs and
mostly just defaults on the 4900Ms. The ASRs are originating defaults via BGP
but on reload they are blackholing traffic whilst BGP converges.
I've seen that OSPF and ISIS have 'wait-for-bgp' overload bits available and
have been questioning whether switching to an IGP-generated default with
wait-for-bpg is the correct solution here. Any thoughts?
Thanks,
Tom
