In this post i will share VPLS BGP Configuration in Juniper router.
Requirements:
- In Juniper you have to used Tunnel Service PIC (VT interface). If you don’t have any Tunnel PIC, you have to configure no-tunnel-services in the routing-instance. No-tunnel-services has limitation in several PIC in Junos 8.0
NOTE: The following interface types do not support the use of LSI interfaces with VPLS:
- Aggregated SONET/SDH (cannot be used as the core-facing interface)
- 1-port Gigabit Ethernet
- 2-port Gigabit Ethernet
- 4-port Fast Ethernet
However, I cannot see the documentation of this limitation in Junos 8.3
NOTE: The following interface types do not support the use of LSI interfaces with VPLS:
- Aggregated SONET/SDH interfaces (cannot be used as the core-facing interface)
- Channelized interfaces (cannot be used as the core-facing interface)
- ATM1 interfaces
Below is the configuration topology which is related with my work in VPLS BGP.
IP Address:
PE1 Lo0: 1.1.1.1/32
PE2 Lo0: 2.2.2.2/32
PE3 Lo0: 3.3.3.3/32
CE1, CE2 and CE3 has one subnet address.
CE1 interface: 11.0.0.1/24
CE2 interface: 11.0.0.2/24
CE3 interface: 11.0.0.3/24
RR Lo0: 4.4.4.4/32
IGP using OSPF area 0.0.0.0.
VPLS Interface Configurations:
PE1 to CE1 Interface
interfaces {
ge-3/3/0 {
encapsulation ethernet-vpls;
unit 0;
}
PE2 to CE2 Interface
interfaces {
ge-1/1/0 {
encapsulation ethernet-vpls;
unit 0;
}
PE3 to CE3 Interface
interfaces {
ge-2/0/1 {
encapsulation ethernet-vpls;
unit 0;
}
BGP Configuration:

}
cluster 1.1.1.1;
neighbor 1.1.1.1;
neighbor 2.2.2.2;
neighbor 3.3.3.3;
}
}
PE1:

}
}
PE2:
bgp {

}

}
Routing-Instance Configuration:
PE1:
routing-instances {
vpls {
instance-type vpls;
interface ge-3/3/0.0;
route-distinguisher 10:10;
vrf-target target:10:10;
protocols {
vpls {
site-range 50;
site pe1 {
site-identifier 1;
interface ge-3/3/0.0;
}
}
}
}
PE2:
routing-instances {
vpls {
instance-type vpls;
interface ge-1/1/0.0;
route-distinguisher 10:10;
vrf-target target:10:10;
protocols {
vpls {
site-range 50;
site pe2 {
site-identifier 2;
interface ge-1/1/0.0;
}
}
}
}
PE3:
routing-instances {
vpls {
instance-type vpls;
interface ge-2/0/1.0;
route-distinguisher 10:10;
vrf-target target:10:10;
protocols {
vpls {
site-range 50;
tunnel-services {
primary vt-2/3/0;
}
site pe2 {
site-identifier 3;
interface ge-2/0/1.0;
}
}
}
}
Show route from PE1:
CE1_Juniper# run show route
inet.0: 10 destinations, 10 routes (10 active, 0 holddown, 0 hidden)
+ = Active Route, – = Last Active, * = Both
10.1.1.0/24 *[Direct/0] 15:56:05
> via ge-1/0/0.10
10.1.1.2/32 *[Local/0] 15:56:05
Local via ge-1/0/0.10
11.0.0.0/24 *[Direct/0] 14:28:56
> via ge-1/0/0.600
11.0.0.1/32 *[Local/0] 14:28:56
Local via ge-1/0/0.600
11.11.11.11/32 *[Direct/0] 1d 21:31:28
> via lo0.0
