IPv6 BGP Commands
BGP is an external gateway protocol that transmits interdomain routing information within and between autonomous systems (AS). BGP
version 4 (BGPv4) supports classless interdomain routing and the aggregation of routes and AS paths. Basically, two routers (called
neighbors or peers) exchange information including full routing tables and periodically send messages to update those routing tables.
The following commands allow you to configure and enable BGP.
address family
This command changes the context to subsequent address family identifier (SAFI).
Syntax
address family ipv6 unicast
To remove SAFI context, use the no address family ipv6 unicast command.
Parameters
ipv6 Enter the keyword ipv6 to specify the address family as IPv6.
unicast Enter the keyword unicast to specify multicast as SAFI.
Defaults IPv6 Unicast
Command Modes ROUTER BGPV6-ADDRESS FAMILY
Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
After this command is executed, all subsequent commands apply to this address family. You can exit from this
AFI/SAFI to the IPv6 Unicast (the default) family by entering the exit command and returning to the Router
BGP context.
aggregate-address
Summarize a range of prefixes to minimize the number of entries in the routing table.
Syntax
aggregate-address ipv6-address prefix-mength [advertise-map map-name] [as-set]
[attribute-map map-name] [summary-only] [suppress-map map-name]
Parameters
ipv6-address
prefix-length
Enter the IPv6 address in the x:x:x:x::x format then the prefix length in the / x format.
The range is from /0 to /128.
