Agreed. However, if the relay is configured to use option 82 sub option 5 (RFC3527), the relay can overwrite the giaddr to an IP that is reachable by the DHCP server (typically the egress interface instead of the ingress interface). The relay would also inserts the link subnet into the option 5 field, and the server uses that value to select the subnet it should allocate from, instead of using giaddr to signal that.
I am assuming that IOS does not do this on a "global" IP helper, then? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
