You can include this statement at the following hierarchy levels:

•

[edit interfaces interface-name unit unit-number]

•

[edit logical-systems logical-system-name interfaces interface-name unit unit-number]

NOTE: The [edit logical-systems] hierarchy level is not applicable in ACX

Series routers.

If you have configured the Layer 3 VPN to handle both IPv4 and IPv6 routes, configure

the interface to handle both IPv4 and IPv6 routes by including the unit statement:

unit unit-number {

family inet {

address ipv4-address;

}

family inet6 {

address ipv6-address;

}

You can include this statement at the following hierarchy levels:

•

[edit interfaces interface-name]

•

[edit logical-systems logical-system-name interfaces interface-name]

NOTE: The [edit logical-systems] hierarchy level is not applicable in ACX

Series routers.

Configuring EBGP Multihop Sessions Between PE and CE Routers in Layer 3 VPNs

You can configure an EBGP or IBGP multihop session between the PE and CE routers of

a Layer 3 VPN. This allows you to have one or more routers between the PE and CE

routers. Using IBGP between PE and CE routers does not require the configuration of any

additional statements. However, using EBGP between the PE and CE routers requires

the configuration of the multihop statement.

To configure an external BGP multihop session for the connection between the PE and

CE routers, include the multihop statement on the PE router. To help prevent routing

loops, you have to configure a time-to-live (TTL) value for the multihop session:

multihop ttl-value;

For the list of hierarchy levels at which you can configure this statement, see the summary

section for this statement.
