https://community.extremenetworks.com/t5/extremeswitching-exos-switch/transmitting-received-bgp-routes-with-as-in-tact/m-p/44923#M11108 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.<BR /> <BR /> 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.<BR /> <BR /> 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!

I think I found a few things out which might help the community...some might not.<BR /> <BR /> The ultimate cure was to add:<BR /> configure bgp add network SMALLERSUB/NET<BR /> <BR /> modify aggregate address to remove SMALLERSUB/NET from aggregation:<BR /> configure bgp add aggregate-address LARGERSUB/NET summary-only advertise-policy RemoveSummary<BR /> <BR /> edit RemoveSummary.pol<BR /> entry removefromsummary {<BR /> if match any {<BR /> nlri SMALLERSUB/NET exact;<BR /> } then {<BR /> deny;<BR /> }<BR /> }<BR /> <BR /> entry accept_others {<BR /> if { } then {<BR /> permit;<BR /> }<BR /> }<BR /> <BR /> 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. <BR /> <BR /> Hope this info helps somebody!<BR /> <BR /> Tue, 27 Nov 2018 04:55:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/transmitting-received-bgp-routes-with-as-in-tact/m-p/44925#M11110 nesuser2 2018-11-27T04:55:00Z
