BGP / CCNP R&S ROUTE: Implementing IP Routing

[JMarquez99]

If our goal is to aggregate 2001:0DB8:0:0::/64 to 2001:0DB8:0:35::/64 as a single, summarized route, write the full aggregation command to perform this. 
Router(config-router)#

Does anyone know what will be the full aggregation command to perform this?
Hoping to have your feedback
TIA

Hello @JMarquez99 ,

you can aggregate checking the bits or hexadecimal digits in common.

Hex 35 -> 00|110101

Hex 00 -> 00|000000

You need to shrink the prefix length of six binary digits so your aggregate address will be

aggregate-address 2001:0DB8:0:0::/58

and will cover subnets up to 2001:0DB8:0:3F::/64.

So this is an approximate solution called in some books an inclusive summary route as it includes some additional subnets.

Hope to help

Giuseppe
