Cisco IOS XR Routing Configuration Guide
Applying Policy When Updating the Routing Table
Perform this task to apply a routing policy to routes being installed into the routing table.
Prerequisites
See the Implementing Routing Policy on Cisco IOS XR Software module of Cisco IOS XR Routing
Configuration Guide for a list of the supported attributes and operations that are valid for table policy
filtering.
SUMMARY STEPS
1. configure
2. router bgp as-number
3. address-family {ipv4 unicast | ipv4 multicast | ipv6 unicast | ipv6 multicast}
Step 15
clear bgp {ipv4 {unicast | multicast |
labeled-unicast | all} | ipv6 {unicast |
multicast | all | labeled-unicast} | all
{unicast | multicast | all | labeled-unicast} |
vpnv4 unicast | vrf {
vrf-name
| all} {ipv4
{unicast | labeled-unicast} | ipv6 unicast} |
vpnv6 unicast} flap-statistics
ip-address
/
mask-length
Example:
RP/0/RP0/CPU0:router# clear bgp ipv4 unicast
flap-statistics 172.20.1.1
Clears BGP flap statistics for routes received from the
specified neighbor.
Step 16
show bgp [ipv4 {unicast | multicast |
labeled-unicast | all} | ipv6 {unicast |
multicast | all | labeled-unicast} | all
{unicast | multicast | all | labeled-unicast} |
vpnv4 unicast [rd
rd-address
] | vrf {
vrf-name
|
all} [ipv4 {unicast | labeled-unicast} | ipv6
unicast] | vpnv6 unicast [rd
rd-address
]]
dampened-paths
Example:
RP/0/RP0/CPU0:router# show bgp dampened paths
Displays the dampened routes, including the time
remaining before they are unsuppressed.
Step 17
clear bgp {ipv4 {unicast | multicast |
labeled-unicast | all} | ipv6 {unicast |
multicast | all | labeled-unicast} | all
{unicast | multicast | all | labeled-unicast} |
vpnv4 unicast | vrf {
vrf-name
| all} {ipv4
{unicast | labeled-unicast} | ipv6 unicast} |
vpnv6 unicast} dampening
[
ip-address/mask-length
]
Example:
RP/0/RP0/CPU0:router# clear bgp dampening
Clears route dampening information and unsuppresses the
suppressed routes.
