I am having an issue with what appears to be two networks that are advertised to me via BGP..one is pretty standard and the other one is maybe a little less typical. I receive the route from an EBGP peer for a /24 and it goes into our routing table. When I advertise these upstream, there is no record of the source ASN. To complicate things further, one of the peers is using a SWIP'd range which is fine but it is part of an aggregate network that we advertise. I have an advertisement policy that removes that from the summary but so far that doesn't seem to be working.

To recap, networks that I receive via an EBGP customer are not being transmitted to other EBGP peers even when permitted and I am hoping to retain the ASN so that when it gets further upstream it has the full AS-path.

Let me know what details I can share but so far I'm not finding any gtac guides or any similar requests on the community site. Thank you!

Can you post the running configuration of bgp

Padmashree, Thanks for your reply. I think I found a few things out which might help the community...some might not.

The ultimate cure was to add:
configure bgp add network SMALLERSUB/NET

modify aggregate address to remove SMALLERSUB/NET from aggregation:
configure bgp add aggregate-address LARGERSUB/NET summary-only advertise-policy RemoveSummary

edit RemoveSummary.pol
entry removefromsummary {
if match any {
nlri SMALLERSUB/NET exact;
} then {
deny;
}
}

entry accept_others {
if { } then {
permit;
}
}

Last but not least, one of my routers was routers was kicking out the route received from an ebgp peer..haven't had the time to look at release notes but I suspect it is a previously addressed bug.

Hope this info helps somebody!
