Cisco ASR 9000 Series Routing Configuration Guide

PurposeCommand or Action
Specifies the attribute-filter group name and enters the attribute-filter
group configuration mode, allowing you to configure a specific
attribute filter group for a BGP neighbor.
attribute-filter group attribute-filter group
name
Example:
RP/0/RSP0/CPU0:router(config-bgp)#
attribute-filter group ag_discard_med
Step 3
Specifies a single or a range of attribute codes and an associated action.
The allowed actions are:
attribute attribute code { discard |
treat-as-withdraw }
Example:
RP/0/RSP0/CPU0:router(config-bgp-attrfg)#
attribute 24 discard
Step 4
• Treat-as-withdraw— Considers the update message for
withdrawal. The associated IPv4-unicast or MP_REACH NLRIs,
if present, are withdrawn from the neighbor's Adj-RIB-In.
• Discard Attribute— Discards this attribute. The matching
attributes alone are discarded and the rest of the Update message
is processed normally.
Configuring BGP Next-Hop Trigger Delay
Perform this task to configure BGP next-hop trigger delay. The Routing Information Base (RIB) classifies
the dampening notifications based on the severity of the changes. Event notifications are classified as critical
and noncritical. This task allows you to specify the minimum batching interval for the critical and noncritical
events.
