R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

428
To specify the address of an indirectly connected interface as the source address, use the peer
ebgp-max-hop command. The command allows the establishment of an EBGP session to the indirectly
connected peer.
You can specify both a source IP address and a source IPv6 address for a peer group. BGP uses the
source IP address to establish TCP connections to IPv4 peers in the group. It also uses the source IPv6
address to establish TCP connections to IPv6 peers in the group.
Examples
# In BGP view, specify the source IP and IPv6 addresses 1.1.1.1 and 1::1 for the peer group test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test source-address 1.1.1.1 1::1
# In BGP-VPN instance view, specify the source IP and IPv6 addresses 1.1.1.1 and 1::1 for the peer group
test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer test source-address 1.1.1.1 1::1
