Hi,The VTEP learns about other VTEPS, is it only via the originating router IP in the T3 route prefix?How the T2 route nexthop is handled in the clos topology with E-BGP sessions between leaf & spines, is it modified at every hop ? Thanks
For IP we have prefix-list and ACL, I am aware of difference between them.For MAC ACL already exists, do we have the prefix-list equivalent for MAC addresses ?For example: to use in BGP EVPN route filtering using host MAC address
I have one general BGP question and like to know how this problem is addressedMy topology has 4 BGP speakers, each in different AS number. Mesh topology between this routers:Each router has eBGP session with other routersR1-----------------R4| ...
My question is regarding BGP EVPN overlay sessions between spine & leaf nodes being E-BGP sessions, in this case the MAC-IP route received by the spine node, does it set nexthop to self before forwarding this update message ?
thank you @MHM Cisco World I missed the point that R3 would send the withdraw to R4, because only leftover path is the one that it learnt from R4.And yes as-path loop avoid is also possible, so some update received (with its own AS in AS-PATH list) i...
why would the R4 delete the route-path received from R3 when it receives withdraw from R1. Route-path from R3 is valid till it receives withdraw from R3.when both routers R3 & R4 receive the withdraw from R1. They still keep path from each other as v...
yes same topology, repro of the issue depends on the order of withdraws received by R3 & R4If R3 & R4 receive withdraw from R1 & R2 first, then issue is seen I think.Is there any solution for this possible deadlock issue in BGP standard?
@R4:time-1>path1: AS-PATH (100), NH (R1), received directly from R1path2: AS-PATH (200,100), NH (R2), received from R2, R2 received it from R1path3: AS-PATH (300,100), NH (R3), received from R3, R3 received it from R1time-2: R4 receives withdraw from...
