Just got done reading about nested QOS maps and one blurb I read indicated one should be careful not to define a catch all "IP Any Any" ACL for the default class. They sited that the reason was you would then exclude all your routing protocol traffic like BGP and EIGRP, etc.
They suggested if you must do that becasue your traffic is too varried to ACL everything, at least ACL the BGP and other routing protocols. What no one said though is, what class should you assign that too?
The config at this site does exactly that...sets up three ACLs one for voip/VTC as EF; one for special applications as AF41 and all other (match IP any any) as AF31. There's a 'default class' but it gets best effort. Looking at the ACL's that's where the BGP stuff would fall. Maybe that, and the fact that the bandwidth left over for the default class is like 1% of a 6 MB link explains why BGP is so slow to converge for these folks.
Anyway, the question is, suppose I set up a class for BGP...what class would I give it (not EF surely but maybe some AF level?) How much BW might one small 6-site MPLS network need? I'm about to just toss it in there with the lesser applications...af31 in this case.
