• Tears down the BGP session to the peer or peer group and, after a specified period of time,
re-establishes a BGP session to the peer or peer group.
You can specify a percentage threshold for the router to generate a log message. When the ratio of the
number of received routes to the maximum number reaches the percentage value, the router generates a
log message.
To limit routes that a router can receive from a peer or peer group (IPv4):
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view or BGP-VPN
instance view.
• Enter BGP view:
bgp as-number
• Enter BGP-VPN instance view:
a. bgp as-number
b. ip vpn-instance
vpn-instance-name
N/A
3. Enter BGP IPv4 unicast
address family view or
BGP-VPN IPv4 unicast
address family view.
address-family ipv4 [ unicast ] N/A
4. Specify the maximum number
of routes that a router can
receive from a peer or peer
group.
peer { group-name | ip-address
[ mask-length ] } route-limit
prefix-number [ { alert-only |
discard | reconnect
reconnect-time } |
percentage-value ] *
By default, the number of routes
that a router can receive from a
peer or peer group is not limited.
To limit routes that a router can receive from a peer or peer group (IPv6):
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter BGP IPv6 unicast
address family view.
address-family ipv6 [ unicast ] N/A
4. Specify the maximum number
of routes that a router can
receive from a peer or peer
group.
peer { group-name | ipv6-address
[ prefix-length ] } route-limit
prefix-number [ { alert-only |
discard | reconnect
reconnect-time } |
percentage-value ] *
By default, the number of routes
that a router can receive from a
peer or peer group is not limited.
Configuring BGP route filtering policies
Configuration prerequisites
Before you configure BGP routing filtering policies, configure the following filters used for route filtering
as needed:
• ACL (see ACL and QoS Configuration Guide).
