[c-nsp] XR 12000/GSR - 4.2.3 VRRP IPv6 Global virtual address.

[Xu Hu]

one recommendation is that check the ttl value for xr and junos.
I got one case regarding iOS & IOS-XR, then cannot talk, finnaly i sniffer
the detail packet and found that the default ttl value is different, so
both cannot recognise each other.
