R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

395
Description
Use peer connect-interface to specify the source interface for establishing TCP connections to a
peer/peer group.
Use undo peer connect-interface to restore the default.
By default, BGP uses the outgoing interface of the best route to the BGP peer/peer group as the source
interface for establishing a TCP connection to the peer/peer group.
Suppose interface A on the local device is connected to interface B on the peer device. When you use
the peer x.x.x.x as-number as-number command on the local device but x.x.x.x is not the IP address of
interface B
, you need to execute the peer connect-interface command on the peer to specify the source
interface (the owner of IP address x.x.x.x) for establishing TCP connections.
To establish multiple BGP connections to another BGP router, you need to specify on the local router the
respective source interfaces for establishing TCP connections to the peers on the peering BGP router;
otherwise, the local BGP router may fail to establish TCP connections to the peers when you use the
outgoing interfaces of the best routes as the source interfaces.
Examples
# In BGP view, specify loopback 0 as the source interface for routing updates to the peer group test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test connect-interface loopback 0
# In BGP-VPN instance view, specify loopback 0 as the source interface for routing updates to the peer
group test (the VPN has been created).
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family vpn-instance vpn1
[Sysname-bgp-vpn1] peer test connect-interface loopback 0
peer default-route-advertise (BGP/BGP-VPN instance view)
Syntax
peer { group-name | ip-address } default-route-advertise [ route-policy route-policy-name ]
undo peer { group-name | ip-address } default-route-advertise
View
BGP view, BGP-VPN instance view
Default level
2: System level
Parameters
group-name: Name of a peer group, a string of 1 to 47 characters.
ip-address: IP address of a peer.
route-policy-name: Routing policy name, a case-sensitive string of 1 to 63 characters.
Description
Use peer default-route-advertise to advertise a default route to a peer/peer group.
Use undo peer default-route-advertise to disable default route advertisement to a peer/peer group.
