show update-groups summary was mislabeled. What it displays is not a summary
at all, but the detailed info about all update-groups. Furthermore, there
was no way to get detailed info about a specific subgroup.
This patch renames "show * update-groups summary" to "show * update-groups"
and adds an option to see the info specific to a subgroup only. It also
validates the subgroup-id.
show * update-groups summary will be added separately.
This patch implements the 'update-groups' functionality in BGP. This is a
function that can significantly improve BGP performance for Update generation
and resultant network convergence. BGP Updates are formed for "groups" of
peers and then replicated and sent out to each peer rather than being formed
for each peer. Thus major BGP operations related to outbound policy
application, adj-out maintenance and actual Update packet formation
are optimized.
BGP update-groups dynamically groups peers together based on configuration
as well as run-time criteria. Thus, it is more flexible than update-formation
based on peer-groups, which relies on operator configuration.
[Note that peer-group based update formation has been introduced into BGP by
Cumulus but is currently intended only for specific releases.]
