[no] neighbor ipv4 timers <
0..65535> < 0..65535>
Sets the interval between each Keepalive message sent by the Zyxel
Device and the maximum time the Zyxel Device waits to receive a
Keepalive message from a peer BGP router before it declares that the
peer BGP router is dead. The interval should be less than the wait time.
The
no command clears the timers.
[no] neighbor ipv4 connect-retry
Sets the number of times the Zyxel Device tries to connect to a peer
BGP router before it declares that the peer BGP router is dead.
The
no command clears the setting.
[no] neighbor ipv4 maximum-prefix <
1..4294967295 >
Sets the maximum number of prefixes, from 1 to 4294967295, of prefixes
that can be received from a neighbor. A prefix is a network address
(IP/subnet mask) that a BGP router can reach and that it shares with its
neighbors. This limits the number of prefixes that the Zyxel Device is
allowed to receive from a neighbor. If extra prefixes are received, the
Zyxel Device ends the connection with the peer BGP router. You need
to edit the peer BGP router configuration to bring the connection
back.
The
no command clears the maximum number of prefixes.
[no] neighbor ipv4 ttl-security
[hops] <1..254>
Sets the maximum number of hops (1 to 254) between the Zyxel Device
and a peer BGP router. The Zyxel Device will only accept incoming IP
packets with a TTL value that is equal to or greater than the expected
value. If the hop count is 3, then the expected incoming TTL value is at
least 252, which is 255 minus the TTL value of 3. The Zyxel Device will only
accept incoming IP packets from a peer BGP router if it is up to 3 hops
away.
The
no command clears the hop count.
[no] neighbor ipv4 default-originate
Allows the Zyxel Device to send the default route 0.0.0.0 to peer BGP
router for use as a default route.
The
no command sends no route as a default.
[no] neighbor ipv4 password password
Sets a default password for MD5 authentication of communication
between the Zyxel Device and the peer BGP router. The password can
consist of alphanumeric characters and the underscore, and it can be
up to 16 characters long.
The
no command clears the password.
[no] neighbor ipv4 update-source
[ipv4|interface_name]
Allows BGP sessions to use the specified Zyxel Device gateway IP
address or Zyxel Device interface for TCP connections.
The
no command clears the interface.
show bgp [global |neighbor]

show bgp [summary | route | mem]
Displays BGP run time route and memory status.
show ip bgp neighbor ipv4
[advertised-routes | prefix-counts |
routes]
Displays route information to the specified peer BGP router.
show ip route bgp

persist information.
