I think that the OP and also another person were under the impression that they can get a default from the DHCP server. DHCPv6 does not currently provide a default route to clients. There has been a fairly spirited argument on the NANOG list re: whether the decision not to include an option for setting a default route via DHCPv6 was right or wrong. My personal opinion is that this feature should have been part of DHCPv6 from the very beginning - for the sake of feature parity between DHCPv4 and DHCPv6 - but I was not a part of those discussions. jms ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
Re: [c-nsp] DHCPv6
There's finally discussion and documentation for DHCPv6 to provide more than just a client address and on the flip side ( and the other stupidity) extensions so that SLAAC can provide eg DNS servers and NTP server details which will finally make it more auto config and mean no more dual stack SLAAC+DHCPv4 shenanigans Alan -- Sent from my Android device with K-9 Mail.

Been a while since I looked at it in a sniffer. Having a different packet format for IPv6 makes sense, as, uh, it's not IPv4 anyway :-) - but forcing me to move our IPv4 HSRP groups to v2 (which incurs a reachability hit) to be able to enable *different* HSRP groups for IPv6 later on is just so slightly annoying. [..] HSRP has a lot of weird edge cases on Cisco gear. IIRC a lot of them relate to the size of the CPU MAC-address receive filter, and other tedious crap that wouldn't matter if they moved off CPUs from last millenium. True. Plus programmers that have never worked with a real network, where things actually *evolve* over time... [..] In fairness to Cisco, other vendors have blind spots. Juniper makes you type a truly tedious amount of config to get VRRP working, though at least commit scripts can automate that out of existence.

[c-nsp] Citrix Netscalers with Cisco port channels

Re: [c-nsp] Citrix Netscalers with Cisco port channels
I'm not sure what model switch it's connected to but some of my coworker's recently opened a case with Citrix because the Netscaler was rebooting and the port channel wouldn't come back up after the reboot. I believe one of the interfaces would flap if I remember correctly. It's been sent to Citrix's escalation team but so far they've said that there's no fix.
