When using any route map, EVPN type 3 (multicast) routes are not advertised.
Apply the configuration to reproduce the problem:
interfaces { bridge br100 { mac 26:28:B0:96:C0:CA member { interface vxlan100 { } } vrf internet } vxlan vxlan100 { mtu 1500 parameters { nolearning } port 4789 source-address 10.32.0.43 vni 100 } } policy { route-map RS-OUT { rule 10 { action permit } } } } protocols { bgp { address-family { l2vpn-evpn { advertise-all-vni vni 100 { advertise-svi-ip rd 65023:100000100 route-target { export 65002:1 import 65000:100 } } } } neighbor 10.32.1.2 { peer-group RS-EVPN } parameters { log-neighbor-changes router-id 10.32.0.41 } peer-group RS-EVPN { address-family { l2vpn-evpn { route-map { export RS-OUT } } } capability { extended-nexthop } ebgp-multihop 32 remote-as 65020 update-source dum0 } system-as 65023 } }
Checking the route:
vtysh -c "show bgp l2vpn evpn route rd 65023:100000100 type 3" EVPN type-1 prefix: [1]:[EthTag]:[ESI]:[IPlen]:[VTEP-IP]:[Frag-id] EVPN type-2 prefix: [2]:[EthTag]:[MAClen]:[MAC] EVPN type-3 prefix: [3]:[EthTag]:[IPlen]:[OrigIP] EVPN type-4 prefix: [4]:[ESI]:[IPlen]:[OrigIP] EVPN type-5 prefix: [5]:[EthTag]:[IPlen]:[IP] BGP routing table entry for 65023:100000100:[3]:[0]:[32]:[10.32.0.43] Paths: (1 available, best #1) Not advertised to any peer Route [3]:[0]:[32]:[10.32.0.43] VNI 100 Local 10.32.0.43 from 0.0.0.0 (10.32.0.41) Origin IGP, weight 32768, valid, sourced, local, best (First path received) Extended Community: ET:8 RT:65002:1 Last update: Tue Jun 13 14:58:40 2023 PMSI Tunnel Type: Ingress Replication, label: 100 Displayed 1 prefixes (1 paths) with this RD (of requested type)
This route is not advertised to any peer. As a result, any multicast and broadcast traffic is not routed.
If I turn off the route map, the problem with route advertising goes away:
delete protocols bgp peer-group RS-EVPN address-family l2vpn-evpn route-map export commit exit
Checking the route:
