NOTE
The show commands implemented for BGP4+ correspond to the show commands implemented for
IPv4 BGP. For example, you can specify the show ipv6 bgp command for IPv6 and the show ip bgp
command for IPv4. Also, the displays for the IPv4 and IPv6 versions of the show commands are
similar except where relevant, IPv6 neighbor addresses replace IPv4 neighbor addresses, IPv6
prefixes replace IPv4 prefixes, and IPv6 next-hop addresses replace IPv4 next-hop addresses.
Displaying the BGP4+ route table
BGP4+ uses filters you define, as well as an algorithm to determine the preferred route to a
destination. BGP4+ sends only the preferred route to the device’s IPv6 table. However, if you want to
view all the routes BGP4+ knows about, you can display the BGP4+ table.
To display the BGP4+ route table, enter the following command at any level of the CLI.
device# show ipv6 bgp routes

show ipv6 bgp routes output descriptions TABLE 104
Field Description
Number of
BGP4+ Routes The number of routes displayed by the command.
Status codes A list of the characters the display uses to indicate the route’s status. The status code appears
in the Status column of the display. The status codes are described in the command’s output.
Prefix The route’s prefix.
Next Hop For normal IPv6 routes, next hop is the next hop IPv6 router to reach the destination. For the
6PE routes, next hop is the IPv4-mapped IPv6 address of the peer 6PE router.
Metric The value of the route’s MED attribute. If the route does not have a metric, this field is blank.
LocPrf The degree of preference for the advertised route relative to other routes in the local AS. When
the BGP4+ algorithm compares routes on the basis of local preferences, the route with the
higher local preference is chosen. The preference can have a value from 0 - 4294967295.
