Ipv6 bgp table

Still small and growing as a snail rate;> show route protocol bgp table inet6.0

inet6.0: 21117 destinations, 314572 routes (21117 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

This year in 2015 we should see more ipv6 networks becoming active as more migrations and new networks are populated over ipv6 vrs ipv4.

Also keep in the back of your mind that the  ipv4 table is way over half-million routes so you might need to adjust your l3 profiles for ipv4-unicast routes received. Smaller platforms with less memory are more effected.

In IOS-XR you need to be in admin and config t and  you can adjust the scale;

hw-module profile scale

hw-module profile scale ?
  default  Default scale profile
  l3       L3 scale profile
  l3xl     L3 XL scale profile

You can monitor  the  usages by using the show cef comamnds;


show cef summary location 0/0/CPU0 

show cef resource location


show cef platform resource summary location 0/0/CPU0
