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).

# 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).
