from ... to
Specifies the link or node to be added to an SRLG.
Syntax: [no] from ipAddress [to ipAddress]
Description: Links and nodes are added to an SRLG from within the external SRLG command mode for that SRLG.
Use the from command to add a node to an SRLG by identifying the IP address for the desired node. If IP address is a router ID, the SRLG applies to all links coming to the specified router. If the router specified is the ingress, the SRLG has no affect, since an ingress can not protect itself from its own failure. When only using the from command, only specify a router ID or subnet (pseudonode). Specifying an interface ID is not supported for the from only command.
Use the from to command to identify a link by identifying the IP address of both ends of the link. The specification of a link is bidirectional. Specifying from a to b configures both directions in a single command. If a to b is already configured, specifying b to a will return an error indicating the configuration already exists.
Use the no from [to] command to remove a link or node from an SRLG.
Factory Default: None.
Command Mode: External-srlg.
Example: In the following example, the from command adds node 50.50.1.0 and link 50.50.2.1 50.50.2.4 to SRLG 1 for this PLR:
router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#external-srlg 1
router(external-srlg)#from 50.50.1.0
router(external-srlg)#from 50.50.2.1 to 50.50.2.4
router(external-srlg)#end
router#show srlg-name
srlg-name no name * 1
router#show external-srlg 1
external-srlg 1
from 50.50.1.0
from 50.50.2.1 to 50.50.2.4
