BGP recursion host
I am trying to understand the influence of "bgp recursion host" command but I am afraid that I am missing something. As far as I understand it literally instructs the BGP process to use only /32 prefixes for BGP next-hop resolution.
In SPv3 workbook Full Scale Lab 4 Task 4.7 "bgp recursion host" is set for VPNv4 address family along with "bgp additional-paths install". Why is "bgp recursion host" necessary here? When we are using VPNv4 address family we are using only /32 routes for hext-hop recursion anyway, why we should explicitly configure this only in this scenario?
Looking forward to getting your comments.
