Setting The Maximum Size Of Update Messages - Juniper JUNOSE SOFTWARE FOR E SERIES 11.0.X - BGP AND MPLS CONFIGURATION GUIDE 2009-12-30 Configuration Manual

Setting the Maximum Size of Update Messages

You can use the neighbor maximum-update-size command to set the maximum
size of update messages transmitted to a BGP peer.
For example, to set the maximum update size to 2,000 octets:
neighbor maximum-update-size
Use to enable MD5 authentication on a TCP connection between two BGP peers.
If you configure a password for a neighbor, an existing session is torn down and
a new one established.
If you specify a BGP peer group by using the peerGroupName argument, all the
members of the peer group inherit the characteristic configured with this
command unless it is overridden for a specific peer.
If a router has a password configured for a neighbor, but the neighbor router
does not, a message indicating this condition appears on the console while the
routers attempt to establish a BGP session between them.
Similarly, if the two routers have different passwords configured, a message
appears on the console indicating that this condition exists.
Use the 8 keyword to indicate that the password is encrypted (entered in
ciphertext). Use the 0 keyword to indicate that the password is unencrypted
(entered in plaintext).
This command takes effect immediately and automatically bounces the BGP
session.
Use the no version to disable MD5 authentication.
See neighbor password
host1(config)#router bgp 100
host1(config-router)#neighbor 10.12.2.5 maximum-update-size 2000
Use to set the maximum size for transmitted BGP update messages.
Set the maximum-update-size to a range: 256–4096.
The default is 1024 octets.
If you specify a BGP peer group by using the peerGroupName argument, all the
members of the peer group inherit the characteristic configured with this
command unless it is overridden for a specific peer.
BGP always accepts updates of up to 4096 octets, regardless of the setting for
transmitted updated messages.
Applies to all update messages sent after you issue the command.
Use the no version to restore the default value.
See neighbor maximum-update-size.
