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 loopback interfaces to
establish a BGP session, you do not need to configure the
peer ebgp-max-hop
command.
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-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
