Configuring BGP Status Monitoring Between Each UPF and Next-Hop Router
Use the following commands to configure Border Gateway Protocol (BGP) monitoring between each UPF and next-hop router. The command is configured in the SRP Configuration Mode.
configure
context context_name
service-redundancy-protocol
[ no ] monitor bgp context bgp-session-context-name [ nexthop-router-ipv4-address | nexthop-router-ipv6-address ] { vrf bgp-session-vrf-name } { group group-number }
end
NOTES:
-
no : Disables BGP status monitoring on the UPF.
-
bgp context bgp-session-context-name : Specifies the context where BGP peer is configured. bgp-session-context-name specifies the context string.
-
nexthop-router-ipv4-address | nexthop-router-ipv6-address : Specifies the configured BGP peer IPv4 or IPv6 address to monitor.
-
vrf bgp-session-vrf-name : Specifies the BGP VPN Routing and Forwarding (VRF) instance. bgp-session-vrf-name specifies the VRF name.
-
group group-number : Specifies the BGP peer group where the BGP peer should be included. group-number specifies the group number.
On implementing this keyword, the behavior is as follows:
-
If any BGP peer in that group is up, the BGP peer group is up.
Omitting group configuration for a BGP monitor includes that monitor in group 0.
BGP group 0 monitors in a context from an implicit group. Each context forms a separate BGP group 0 implicit monitor group.
If any BGP peer group is down, BGP monitor is down.
-
-
This command is disabled by default.
Alternate Algorithm to Flag BGP monitoring failure
In this release, an alternate (new) algorithm is introduced to flag BGP monitoring failure.
Use the following commands to flag BGP monitor failure on a single BGP peer (User Plane Function) failure. This command is configured in the SRP Configuration Mode.
configure
context context_name
service-redundancy-protocol
[ no ] monitor bgp exclusive-failover
end
NOTES:
-
no : Disables flagging of BGP monitor failure on a single BGP peer failure.
-
On implementing the new exclusive-failover keyword, the behavior is as follows:
-
BGP peer group is Up if any BGP peer in that group is Up.
-
Including a BGP peer in group 0 is same as making it non-group (omitting group).
-
BGP monitor is down if any BGP peer group or any non-group BGP peer is down.
-
-
This command is disabled by default.
