[c-nsp] ME3400 FHRP - GLBP with IPv4 and IPv6

[Calin C.]

Hi,

I did encounter this message only with HSRP and there the problem was
that IPv6 requires version 2 and IPv4 works fine with version 1.

For GLBP...please let me know if you find the answer.

Thanks,
Calin

Hi,

we need a FHRP that support IPv4 and IPv6 one some ME3400s in our
network. The documentation state that GLBP would do that on the MEs but
it seems that it can not be configured on this systems, regardless
whether we are using link local or global unicast IPv6 addresses.

me3400g-2cs(config-if)#glbp 1 ip 10.0.0.1
me3400g-2cs(config-if)#glbp 2 ipv6 FE80::1
%FHRP group not consistent with already configured groups on the switch
stack

I'am wondering if someone can confirm that behavior or have an other
solution.

If there exist no FHRP for ME3400 that supports IPv4 and IPv6 in that
way our last chance is using IPv6 anycast addresses for the
IPv6-redundancy but that would imply much slower convergence
characteristics :-(.


Thx,
Gerald
