/cfg/l3/bgp/peer <peer number>
BGP Peer Configuration Menu
This menu is used to configure BGP peers, which are border routers that exchange routing information with routers on internal and external networks. The peer option is disabled by default.
Two BGP routers become peers, or neighbors, once you establish a TCP connection between them.
Alteon supports TCP establishment by its interface addresses only (Floating IP and VR addresses are not supported).
For each new route, if a peer is configured to connect to that route (for example, if a peer is configured to receive static routes and the new route is static), an update message is sent to that peer containing the new route. For each route removed from the routing table, if the route has already been sent to a peer, an update message containing the route to withdraw is sent to that peer.

BGP Peer Configuration Options (/cfg/l3/bgp/peer) 
Command Syntax and Usage
redist
 
Displays the BGP Redistribution menu. To view this menu, see /cfg/l3/bgp/peer/redist BGP Redistribution Configuration Menu.
ipver <IPv4 or IPv6)
 
Defines the IP version format: IPv4 or IPv6.
Values: v4, v6
addr <IP address (IPv4 or IPv6 format)
 
Defines the IP address (in IPv4 or IPv6 format) for the specified peer (border router.
Default: 0.0.0.0
ras <AS number (0-65535)>
 
Sets the remote autonomous system number for the specified peer.
hold <hold time (0, 3-65535)>
 
Specifies the period of time in seconds that will elapse before the peer session is torn down because Alteon has not received a Keep-Alive message from the peer.
Values: 0, 3 – 65,535
Default: 180
alive <keepalive time (0, 1-21845)>
 
Sets the keep alive time for the specified peer in seconds.
Default: 0
advert <min adv time (1-65535)>
 
Specifies the minimum time in seconds between advertisements of the BGP peer IP datagram.
Default: 60
retry <connect retry interval (1-65535)>
 
Specifies the connection retry interval in seconds of the BGP peer IP datagram.
Values: 1 – 65,535
Default: 120
orig <min orig time (1-65535)>
 
Specifies the minimum time in seconds between route originations of the BGP peer IP datagram.
Values: 1 – 65,535
Default: 30
nexthop
 
Specifies the interface floating IP address, the interface IP address, or the virtual interface router (VIR) that Alteon advertises to BGP peers.
If the advfip command is enabled globally, Alteon advertises the floating IP address to all BGP peers except this peer. Alteon advertises the IP address configured in the nexthop command to this peer.
If no floating IP address is configured in the BGP peer network, Alteon advertises the interface IP address to all BGP peers.
If the floating IP address is not enabled globally, Alteon advertises the interface IP address to all peers except this peer. Alteon advertises the IP address configured in the nexthop command to this peer.
ttl <number of router hops (1-255)>
 
Time-to-live (TTL) is a value in an IP packet that tells a network router whether the packet has been in the network too long and should be discarded. TTL specifies a certain time span in seconds that, when exhausted, causes the packet to be discarded. The TTL is determined by the number of router hops the packet is allowed before it must be discarded.
This command specifies the number of router hops that the IP packet can make. This value is used to restrict the number of hops the advertisement makes. It is also used to support multi-hops, which allow BGP peers to talk across a routed network.
Default: 1
addi <route map ID (1-32)>
 
Adds a route map into the in-route map list.
addo <route map ID (1-32)>
 
Adds a route map into the out-route map list.
remi <route map ID (1-32)>
 
Removes a route map from the in-route map list.
remo <route map ID (1-32)>
 
Removes a route map from the out-route map list.
bfd on|off
 
Specifies whether to enable Bidirectional Forwarding Detection (BFD).
Bidirectional Forwarding Detection (BFD) is a network protocol used to detect faults between Alteon and other routers that are BGP peers or OSPF neighbors. When a BFD session disconnects, BFD clients are updated about the connection status with BGP peers or OSPF neighbors.
Default: off
grcrstrt
 
Specifies whether to enable/disable BGP graceful restart on the peer.
The default value is inherited from the global BGP configuration.
comm
 
Specifies the community attributes- Standard, Extended and/or Large community lists - to be transmitted to the peers.
password
 
Specifies whether to require an authentication password for the BGP peers.
Values: none, password
If Password is selected, you are prompted to enter and confirm a passphrase. (Maximum number of characters: 20)
sechops
 
Specifies the TTL security hop count that separate the two peers.
Valid range: 1-255
ena
 
Enables this peer configuration.
dis
 
Disables this peer configuration.
del
 
Deletes this peer configuration.
cur
 
Displays the current BGP peer configuration.
