9. Configure internal BGP (IBGP).
[edit protocols bgp]
user@PE1# set local-address 192.168.0.101
user@PE1# set group ibgp family inet-vpn any
user@PE1# set group ibgp peer-as 64511
user@PE1# set group ibgp neighbor 192.168.0.102
user@PE1# set group ibgp neighbor 192.168.0.103
10. Configure the Layer 2 circuit on the logical tunnel interface.
Configure the hot-standby-vc-on statement if you want a hot standby pseudowire
to be established upon arrival of PW_FWD_STDBY status TLV.
[edit protocols l2circuit neighbor 192.168.0.100 interface lt-1/2/0.600]
user@PE1# set virtual-circuit-id 1
user@PE1# set pseudowire-status-tlv hot-standby-vc-on
11. Define a pair of conditions to be applied to the egress policy defined within the Layer
3 VPN instance.
In both condition primary and condition standby, the matching route corresponds
to the interface lt-1/2/0.600 (y), as this is the format in which egress routes appear
in routing table mpls.0 to represent any given pseudowire.
The difference between these conditions is in the standby attribute. Upon arrival of
the PW_FWD_STDBY status TLV to Device PE1 or Device PE2, Junos OS matches
condition standby, and in consequence, only term standby within the l3vpn policy
will be executed. On the other hand, if the PW_FWD_STDBY status TLV is not
present, the policy matches only condition primary, which then executes term primary
in the l3vpn policy. Also, for logical tunnel-based CCC services, you must specify
the logical tunnel interface, LT(y), that is associated with the logical tunnel CCC
interface, LT(x). (See “Understanding Pseudowire Redundancy Mobile Backhaul
Scenarios” on page 623.)
Finally, for CCC-based conditions, Junos OS allows only mpls.0 as the matching
routing table. For the address attribute, Junos OS allows only strings with a logical
interface unit format (for example, lt-0/0/0.0).
