Hello @aridy ,
>> Does this have anything to do with having only one RSP card, or is there any way to make BGP neighbors converge quicker when one of the providers goes down?
No, as already noted by other colleagues the addition of a third upstream ISP is not an issue on this kind of platform.
You should provide your router BGP configuration to see if any of the tools to improve convergence are applied.
it would be of interest to understand if BGP next-hop tracking or Prefix Indipendent Convergence PIC can be enabled in this scenario.
The last one is the most efficient way to deal with this kind of scenario.
It would be also interesting to see the output of
show bgp summary
to see how many prefixes are learned from each neighbor.
a full IPv4 internet table is in the order of 880,000 routes now
The router processor should be able to handle millions of prefixes, however the linecards TCAM need to be checked to see if they have smaller capacity. Being a distributed system also the capabilities of linecards are important.
Hope to help
Giuseppe
