IPv6 Border Gateway Protocol (IPv6 BGP)
IPv6 Border Gateway Protocol (IPv6 BGP) is supported on the Dell Networking S5000 switch.
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 configure and enable BGP.
aggregate-address
Summarize a range of prefixes to minimize the number of entries in the routing table.
S5000
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
prefix-length
Enter the IPv6 address in the x:x:x:x::x format followed by the
prefix length in the / x format. The range is /0 to /128.
NOTE: The :: notation specifies successive hexadecimal
fields of zeros.
advertise-map
map-name
(OPTIONAL) Enter the keywords advertise-map followed
by the name of a configured route map to set filters 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.
