eBGP received routes not advertised

Nimrod — Fri, 17 Apr 2020 12:23:13 GMT

Why checkpoint did not advertise routes when the default behavior for eBGP is to advertise all received routes.

version 80.30

fw01> show bgp peer 10.163.63.146 received

IPv4 Route MED LocalPref Nexthop Communities
10.163.1.0/24 None N/A(EBGP) 10.163.63.146

fw01> show bgp peer 10.163.63.210 received

IPv4 Route MED LocalPref Nexthop Communities
10.163.64.6/32 None N/A(EBGP) 10.163.63.211

fw01> show bgp peer 10.163.63.146 advertise

fw01> show bgp peer 10.163.63.210 advertise

fw01> show bgp routemap

Pretty sure routes received via BGP aren't advertised unless you've configured a specific routemap to do that.

Can you paste the configuration of your routemaps " show configuration routemaps"?
