From: Donald Sharp Date: Fri, 22 Mar 2024 20:04:19 +0000 (-0400) Subject: bgpd: Ensure evpn local table display shows route send status X-Git-Tag: base_10.2~133^2 X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=4dd9d1176fbf7f24ffa8438608d1590d67766b3e;p=mirror%2Ffrr.git bgpd: Ensure evpn local table display shows route send status evpn has a concept of `local` tables where the evpn routes are actually converted into underlying routes/neighbor table entries( or vice versa ). Then this local route is propagated to the global evpn l2vpn table and sent to the peers. Certain show commands in evpn look operate on the local table but make the output look like the data has not been sent to the peer. This is confusing for the operator. Modify the code such that local tables get a `Local BGP table not advertised` in the place where the code talks about whom has received the data or not. Example: torm11# show bgp l2vpn evpn route vni 1000 mac 8a:a1:cc:73:a3:ac ip 45.0.0.5 BGP routing table entry for [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5] Paths: (2 available, best #2) Local BGP table not advertised Route [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5] VNI 1000 Imported from 192.168.100.18:2:[2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5], VNI 1000 65101 65005 192.168.100.18(leaf2) from leaf2(192.168.5.1) (192.168.100.14) Origin IGP, valid, external Extended Community: RT:65005:1000 ET:8 Last update: Thu Mar 21 14:29:04 2024 Route [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5] VNI 1000 Imported from 192.168.100.18:2:[2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5], VNI 1000 65101 65005 192.168.100.18(leaf1) from leaf1(192.168.1.1) (192.168.100.13) Origin IGP, valid, external, bestpath-from-AS 65101, best (Router ID) Extended Community: RT:65005:1000 ET:8 Last update: Thu Mar 21 14:29:04 2024 Signed-off-by: Donald Sharp --- diff --git a/bgpd/bgp_evpn_vty.c b/bgpd/bgp_evpn_vty.c index c28cdb4a65..0a5e6a773b 100644 --- a/bgpd/bgp_evpn_vty.c +++ b/bgpd/bgp_evpn_vty.c @@ -2561,7 +2561,7 @@ static void evpn_show_route_vni_multicast(struct vty *vty, struct bgp *bgp, /* Prefix and num paths displayed once per prefix. */ route_vty_out_detail_header(vty, bgp, dest, bgp_dest_get_prefix(dest), - NULL, afi, safi, json, false);
