neighbor maxas-limit in

Causes the device to discard routes received in UPDATE messages if those routes exceed a maximum AS path length.

neighbor { ip-address | ipv6-address | peer-group-name } maxas-limit in { num | disable }
no neighbor { ip-address | ipv6-address | peer-group-name } maxas-limit in
ip-address
Specifies the IPv4 address of the neighbor.
ipv6-address
Specifies the IPv6 address of the neighbor.
peer-group-name
Specifies the peer group name.
num
Specifies the maximum length of the AS path. Valid values range from 0 through 300. The default is 300.
disable
Prevents a neighbor from inheriting the configuration from the peer group or global configuration and instead uses the default system value.

BGP configuration mode

The following example changes the length of the maximum allowed AS path length from the default. 


device# configure terminal
device(config)# router bgp
device(config-bgp-router)# neighbor 10.11.12.13 maxas-limit in 200

The following example prevents a neighbor from inheriting the configuration from the peer group or global configuration and instead use the default system value. 


device# configure terminal
device(config)# router bgp
device(config-bgp-router)# neighbor 2001:2018:8192::125 maxas-limit in disable
