Hello I am deploying EVPN and while it works, we are having some issues. Here is the first one:
An EVPN instance configured for testing on a MX204 and an ACX5448 both running 21.1R1. The have the same exact configuration except for the IP address of the IRB interface: baldur@formervangen-core3# show interfaces irb.20 family inet { address 185.24.168.92/29; } [edit] baldur@formervangen-core3# show routing-instances evpntest instance-type evpn; protocols { evpn; } vlan-id 20; routing-interface irb.20; interface xe-0/0/42.20; vrf-target target:60876:20; [edit] baldur@formervangen-core3# show interfaces xe-0/0/42 flexible-vlan-tagging; encapsulation flexible-ethernet-services; unit 20 { encapsulation vlan-bridge; vlan-id 20; } Also irb.20 is in a layer 3 VRF called "internet". On the MX204 the interface irb.20 comes online but on the ACX5448 the irb.20 interface stays in the state hardware-down: baldur@formervangen-core3# run show interfaces irb.20 Logical interface irb.20 (Index 76) (SNMP ifIndex 563) Flags: Hardware-Down Up SNMP-Traps 0x4004000 Encapsulation: ENET2 Bandwidth: 1Gbps Routing Instance: None Bridging Domain: None Input packets : 0 Output packets: 0 Protocol inet, MTU: 1514 Max nh cache: 100000, New hold nh limit: 100000, Curr nh cnt: 0, Curr new hold cnt: 0, NH drop cnt: 0 Flags: Sendbcast-pkt-to-re, Is-Primary Addresses, Flags: Dest-route-down Is-Preferred Is-Primary Destination: 185.24.168.88/29, Local: 185.24.168.92, Broadcast: 185.24.168.95 Protocol multiservice, MTU: Unlimited In fact I can not get the irb interface to go up at all on the ACX5448 platform. Is IRB unsupported? Without it a lot of EVPN features are not available. In our production environment the mx204 routers do not have any servers directly connected. The irb interface will therefore not come online. But since the acx5448 switches refuse to have their own irb interfaces, I need the mx204 to do the task. My solution right now is to add a dummy interface to the evpn instance on the mx204. Is there a better way? Why did Juniper not include a knop to bring irb up even without any physical interfaces active in the vpn?
