Field Description
Forward Address Identies the address of the forwarding router. Data trac is forwarded to this router. If
the forwarding address is 0.0.0.0, data trac is forwarded to the originating router.
External Route Tag Displays the 32-bit eld attached to each external route. The OSPF protocol does not use
this eld, but you can use the eld for external route management.
