Hello everyone.
I`m having troubles with setting up bgp session over evpn lag. I`ve got two PE`s and one CE switch with CE router connected to it:
EVPN/MPLS routing instance looks similar on both PEs:
instance-type evpn;
vlan-id 404;
interface ae0.404;
routing-interface irb.404;
vrf-target target:51780:404;
protocols {
evpn {
default-gateway no-gateway-community;
}
}
irb interface on PE1:
virtual-gateway-accept-data;
family inet {
address 172.20.5.253/24 {
virtual-gateway-address 172.20.5.1;
}
}
mac 00:22:22:22:04:04;
virtual-gateway-v4-mac 00:00:00:00:04:04;
and on PE2:
virtual-gateway-accept-data;
family inet {
address 172.20.5.254/24 {
virtual-gateway-address 172.20.5.1;
}
}
mac 00:22:22:22:04:04;
virtual-gateway-v4-mac 00:00:00:00:04:04;
So what i`m trying to do - is to set up bgp sessions from PE1(172.20.5.253) to CE router and from PE2(172.20.5.254) to CE router.
in L3VPN instance on both PEs i`ve configured bgp:
PE1:
instance-type vrf;
interface irb.404;
vrf-target target:65100:2000
vrf-table-label;
routing-options {
auto-export;
}
protocols {
bgp {
group SRX {
type external;
local-address 172.20.5.253;
passive;
export SRX-EXPORT;
peer-as 65101;
neighbor 172.20.5.2;
}
}
}
PE2:
instance-type vrf;
interface irb.404;
vrf-target target:65100:2000
vrf-table-label;
routing-options {
auto-export;
}
protocols {
bgp {
group SRX {
type external;
local-address 172.20.5.254;
passive;
export SRX-EXPORT;
peer-as 65101;
neighbor 172.20.5.2;
}
}
}
The result is that i`ve got only one session established (from PE2). Session from PE1 is not establishing, but i can ping PE1(172.20.5.253) from CE router, so as PE2(172.20.5.254).
All routes (172.20.5.253,172.20.5.254, 172.20.5.2) are in vrf instance. type 2 routes are in EVPN/MPLS instance on both PEs:
PE1:
2:10.0.0.2:20::404::00:11:11:11:04:04::172.20.5.253/304 MAC/IP
2:10.0.0.6:20::404::00:22:22:22:04:04::172.20.5.254/304 MAC/IP
2:10.0.0.6:20::404::00:50:56:86:52:2d::172.20.5.2/304 MAC/IP
PE2:
2:10.0.0.2:20::404::00:11:11:11:04:04::172.20.5.253/304 MAC/IP
2:10.0.0.6:20::404::00:22:22:22:04:04::172.20.5.254/304 MAC/IP
2:10.0.0.6:20::404::00:50:56:86:52:2d::172.20.5.2/304 MAC/IP
