IPv6 Border Gateway Protocol (IPv6 BGP)
IPv6 Border Gateway Protocol (IPv6 BGP) is supported on Dell Networking platforms.
This chapter includes the following sections:
• IPv6 BGP Commands
• IPv6 MBGP Commands
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 congure and enable BGP.
aggregate-address
Summarize a range of prexes to minimize the number of entries in the routing table.
Syntax
aggregate-address ipv6-address prefix-length [advertise-map map-name] [as-
set] [attribute-map map-name] [summary-only] [suppress-map map-name]
Parameters
ipv6-address prex-
length
Enter the IPv6 address in the x:x:x:x::x format followed by the prex length in the /
x format. The range is from /0 to /128.
NOTE: The :: notation species successive hexadecimal elds of zeros.
advertise-map
map-name
(OPTIONAL) Enter the keywords advertise-map then the name of a
congured route map to set lters for advertising an aggregate route.
as-set (OPTIONAL) Enter the keywords as-set to generate path attribute information
and include it in the aggregate. AS_SET includes AS_PATH and community
information from the routes included in the aggregated route.
attribute-map map-
name
(OPTIONAL) Enter the keywords attribute-map then the name of a
congured route map to modify attributes of the aggregate, excluding AS_PATH
and NEXT_HOP attributes.
