Flushing The Suboptimal Bgp Route To The Rib; Setting A Dscp Value For Outgoing Bgp Packets - HP FlexFabric 12900E Series Configuration Manual

Step
2. Enter BGP instance view.
3. Configure an update delay for
local MPLS labels.

Flushing the suboptimal BGP route to the RIB

This feature flushes the suboptimal BGP route to the RIB when the following conditions are met:
•
The optimal route is generated by the network command or is redistributed by the
import-route command.
•
The suboptimal route is received from a BGP peer.
After the suboptimal route is flushed to the RIB on a network, BGP immediately switches traffic to the
suboptimal route when the optimal route fails.
For example, the device has a static route to the subnet 1.1.1.0/24 that has a higher priority than a
BGP route. BGP redistributes the static route and receives a route to 1.1.1.0/24 from a peer. After the
flush suboptimal-route command is executed, BGP flushes the received BGP route to the RIB as
the suboptimal route. When the static route fails, BGP immediately switches traffic to the suboptimal
route if inter-protocol FRR is enabled. For more information about inter-protocol FRR, see
"Configuring basic IP
To flush the suboptimal BGP route to the RIB:
Step
1. Enter system view.
2. Enter BGP view.
3. Flush the suboptimal BGP
route to the RIB.

Setting a DSCP value for outgoing BGP packets

The DSCP value of an IP packet specifies the priority level of the packet and affects the transmission
priority of the packet.
To set a DSCP value for outgoing BGP packets:
