Default
BGP does not establish an EBGP session to an indirectly-connected peer or peer group.
Views
BGP view, BGP-VPN instance view
Predefined user roles

Parameters
group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer
group must have been created.
ip-address: Specifies a peer by its IP address. The peer must have been created.
ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created.
hop-count: Specifies the maximum number of hop counts, in the range of 1 to 255. The default is 64.
Usage guidelines
EBGP peers must be directly connected. If not, use the peer ebgp-max-hop command to establish an
EBGP session over multiple hops between two peers.
If direct EBGP peers use indirectly connected interfaces (including loopback interfaces) to establish an
EBGP session, you must perform the following tasks:
• Configure a routing protocol to ensure that a route exists between the two interfaces.
• Configure the peer ebgp-max-hop command to establish the session over multiple hops.
Examples
# In BGP view, enable BGP to establish EBGP sessions to an indirectly-connected EBGP peer group test,
and specify the maximum hop count as 64 (default).
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test ebgp-max-hop
# In BGP-VPN instance view, enable BGP to establish EBGP sessions to an indirectly-connected EBGP
peer group test, and specify the maximum hop count as 64 (default).
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer test ebgp-max-hop
peer enable
Use peer enable to enable BGP to exchange routing information for an address family with a peer or
peer group.
Use undo peer enable to disable BGP from exchanging routing information for an address family with a
peer or peer group.
