472 CHAPTER 36: IPV6 BGP CONFIGURATION
Configuring a Preferred
Value for Routes from a
Peer/Peer Group
To configure a preferred value for routes received from a peer/peer group, use the
following commands:
Specifying a Local
Update Source Interface
to a Peer/Peer Group
To specify a local update source interface connected to a peer, use the following
commands:
n
To improve stability and reliability, you can specify the local interface of an IPv6
BGP connection as loopback interface. By doing so, a connection failure upon
redundancy availability will not affect IPv6 BGP connection.
Configuring a Non Direct
EBGP Connection to a
Peer/Peer Group
To configure an EBGP connection to a peer not directly connected, use the
following commands:
c
CAUTION: In general, direct links should be available between EBGP peers. If not,
you can use the peer ebgp-max-hop command to establish a multi-hop TCP
connection in between. However, you need not use this command for direct EBGP
connection with loopback interfaces.
