Enable Opaque LSA advertisement and reception with the opaque-capability enable command 

before enabling the IETF GR capability for OSPF.  

z 

Before enabling non-IETF GR capability for OSPF, enable OSPF LLS (link local signaling) with the 

enable link-local-signaling command and OOB (out of band resynchronization) with the enable 

out-of-band-resynchronization command.  

z 

If the keywords nonstandard and ietf are not specified when OSPF GR is enabled, nonstandard 

is the default.

acl-number: Basic or advanced ACL number, in the range 2000 to 3999.  

prefix-list: Name of the specified IP prefix list, a string of 1 to 19 characters. 

Use the graceful-restart help command to configure for which OSPF neighbors the current router can 

serve as a GR Helper. (The neighbors are specified by the ACL or the IP prefix list.) 

Use the undo graceful-restart help command to restore the default.  

By default, the router can serve as a GR Helper for any OSPF neighbor.
