Hello,
I have a 7606-S router with an RSP720-3C-GE supervisor and a 7600-ES20-GE3C card. I thought I'd make one of the ports on the RSP a routed port, and connect to the internet and do NAT on this router, but it seems there is no DHCP client functionality available on any of the images for the 7600 series, is that correct?
My ISP provides ip addresses via DHCP only, and I've tried 15.2(4)S4a, 15.3(3)S6, and 15.5(3)S5, but ip address dhcp doesn’t seem to be a valid command on any of them. There are config-if commands referencing dhcp client options, but I get the feeling they're for setting up the relay function.
Is there no way to get an ip address leased via DHCP on an ethernet interface on a 7600 router? I understand that it was developed as an edge router but it just doesn't make sense to me that they would deliberately remove a feature from the service provider train. Is there maybe a workaround using a local pool?
