8.5.9 Checking the Configuration
After the advertising and receiving of BGP4+ routes are controlled, you can check the advertised
routes that match the specified filter.
Prerequisites
The configurations for controlling the advertising and receiving of BGP4+ routing information
are complete.
Procedure
l
Run the
display bgp
ipv6
network
command to check the routes advertised through the
network
command.
l
Run the
display bgp ipv6 routing-table
as-path-filter
{
as-path-filter-number
|
as-path-
filter-name
} command to check the routes matching the specified AS-Path filter.
l
Run the
display bgp ipv6 routing-table
community-filter
{ {
community-filter-name
|
basic-community-filter-number
} [
whole-match
] |
advanced-community-filter-number
}
command to check the routes matching the specified BGP4+ community filter.
l
Run the
display bgp ipv6 routing-table
peer
{
ipv4-address
|
ipv6-address
} {
advertised-
routes
|
received-routes
} [
statistics
] command to check the routing information
advertised or received by the BGP4+ peers.

8.6 Configuring Parameters of a Connection Between BGP4
+ Peers
By setting parameters of a connection between BGP4+ peers, you can adjust and optimize the
BGP4+ network performance.
8.6.1 Establishing the Configuration Task
Before configuring parameters of a connection between BGP4+ peers, familiarize yourself with
the applicable environment, complete the pre-configuration tasks, and obtain the required data.
This can help you complete the configuration task quickly and accurately.
Applicable Environment
After a BGP4+ connection is set up between peers, the peers periodically send Keepalive
messages to each other. This prevents the switches from considering that the BGP4+ connection
is closed. If a switch does not receive any Keepalive message or any type of packets from the
peer within the specified Hold time, the BGP4+ connection is considered as closed.
When a switch sets up a BGP4+ connection with its peer, the switch and the peer need negotiation
with each other. The Hold time after negotiation is the shorter one between the Hold time of the
switch and that of its peer. If the negotiation result is 0, no Keepalive message is transmitted and
whether the Hold timer expires is not detected.
If the value of the timer changes, the BGP4+ connection is interrupted for a short time as the
switch and its peer need negotiate again.
