To configure the BGP prefix peering timeout value, use the following command in router configuration
mode:
Command
timers prefix-peer-timeout value
Example:
switch(config-router-neighbor)# timers
prefix-peer-timeout 120
To configure the maximum number of peers, use the following command in neighbor configuration
mode:
Command
maximum-peers value
Example:
switch(config-router-neighbor)#
maximum-peers 120
This example shows how to configure a prefix peering that accepts up to 10 peers:
switch(config)# router bgp 65536
switch(config-router)# timers prefix-peer-timeout 120
switch(config-router)# neighbor 10.100.200.0/24 remote-as 65536
switch(config-router-neighbor)# maximum-peers 10
switch(config-router-neighbor)# address-family ipv4 unicast
switch(config-router-neighbor-af)#
Use the show ip bgp neighbor command to show the details of the configuration for that prefix peering
with a list of the currently accepted instances and the counts of active, maximum concurrent, and total
accepted peers.

Configuring BGP Authentication

You can configure BGP to authenticate route updates from peers using MD5 digests.
To configure BGP to use MD5 authentication, use the following command in neighbor configuration
mode:
Command
