Notifications

hh3cRibCyclicIterateRestrain

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.219.2.0.1	The recursion loop for routes in the VPN instance is suppressed.	Error	Warning	1.3.6.1.4.1.25506.2.219. 2.0.2 (hh3cRibCyclicIterateRestrainClr)	ON

 

Notification triggers

This notification is generated when the recursion loop for routes in the VPN instance is suppressed.

System impact

The CPU usage might remain high.

Status control

ON

CLI: Use the snmp-agent trap enable [ ipv6 ] rib cyclic-iterate-restrain command.

OFF

CLI: Use the undo snmp-agent trap enable [ ipv6 ] rib cyclic-iterate-restrain command.

Recommended action

To resolve the issue:

1.If the value for 1.3.6.1.4.1.25506.2.219.1.1 (hh3cRibVrfRestrainType) is IPv4, and the value for 1.3.6.1.4.1.25506.2.219.1.3 (hh3cRibVrfIndex) is 0, execute the display ip routing-table command to obtain the route related to 1.3.6.1.4.1.25506.2.219.1.4 (hh3cRibVrfRtNexthopAddress) and identify whether a recursion loop exists.

If yes, proceed to step 5.

If not, proceed to step 6.

2.If the value for 1.3.6.1.4.1.25506.2.219.1.1 (hh3cRibVrfRestrainType) is IPv4, and the value for 1.3.6.1.4.1.25506.2.219.1.3 (hh3cRibVrfIndex) is not 0, execute the display ip routing-table vpn-instance vpn-instance-name command to obtain the route related to 1.3.6.1.4.1.25506.2.219.1.4 (hh3cRibVrfRtNexthopAddress) in VPN routing table hh3cRibVrfName and identify whether a recursion loop exists.

If yes, proceed to step 5.

If not, proceed to step 6.

3.If the value for 1.3.6.1.4.1.25506.2.219.1.1 (hh3cRibVrfRestrainType) is IPv6, and the value for 1.3.6.1.4.1.25506.2.219.1.3 (hh3cRibVrfIndex) is 0, execute the display ipv6 routing-table command to obtain the route related to 1.3.6.1.4.1.25506.2.219.1.4 (hh3cRibVrfRtNexthopAddress) and identify whether a recursion loop exists.

If yes, proceed to step 5.

If not, proceed to step 6.

4.If the value for 1.3.6.1.4.1.25506.2.219.1.1 (hh3cRibVrfRestrainType) is IPv6, and the value for 1.3.6.1.4.1.25506.2.219.1.3 (hh3cRibVrfIndex) is not 0, execute the display ipv6 routing-table vpn-instance vpn-instance-name command to obtain the route related to 1.3.6.1.4.1.25506.2.219.1.4 (hh3cRibVrfRtNexthopAddress) in VPN routing table hh3cRibVrfName and identify whether a recursion loop exists.

If yes, proceed to step 5.

If not, proceed to step 6.

5.Delete the route with recursion loop (for more information, see the configuration guide of the associated routing protocol). Wait for 10 minutes, and identify whether the hh3cRibCyclicIterateRestrainClr alarm occurs and whether the hh3cRibCyclicIterateRestrain alarm does not occur any more.

6.If the issue persists, collect configuration data, log information, and alarm information, and then contact H3C Support for help.
