The format for extended
community-ids
is the following:
type:administrator:assigned-number
type
is the type of extended community and can be either a
bandwidth
,
target
,
origin
,
domain-id
,
src-as
, or
rt-import
community or a 16-bit number that identifies a specific
BGP extended community. The
target
community identifies the destination to which
the route is going. The
origin
community identifies where the route originated. The
domain-id
community identifies the OSPF domain from which the route originated.
The
src-as
community identifies the autonomous system from which the route
originated. The
rt-import
community identifies the route to install in the routing table.
NOTE:
For src-as, you can specify only an AS number and not an IP address.
For rt-import, you can specify only an IP address and not an AS number.
administrator
is the administrator. It is either an AS number or an IPv4 address prefix,
depending on the type of extended community.
assigned-number
identifies the local provider.
The format for linking a bandwidth with an AS number is:
bandwidth:as-number:bandwidth
as-number
specifies the AS number and
bandwidth
specifies the bandwidth in bytes per
second.
NOTE:
In Junos OS Release 9.1 and later, you can specify 4-byte AS numbers
as defined in RFC 4893, BGP Support for Four-octet AS Number Space, as
well as the 2-byte AS numbers that are supported in earlier releases of the
Junos OS. In plain-number format, you can configure a value in the range
from 1 through 4,294,967,295. To configure a target or origin extended
community that includes a 4-byte AS number in the plain-number format,
append the letter “L” to the end of number. For example, a target community
with the 4-byte AS number 334,324 and an assigned number of 132 is
represented as target:334324L:132.
In Junos OS Release 9.2 and later, you can also use AS-dot notation when
defining a 4-byte AS number for the target and origin extended communities.
Specify two integers joined by a period: 16-bit high-order value in decimal.16-bit
low-order value in decimal. For example, the 4-byte AS number represented
in plain-number format as 65546 is represented in AS-dot notation as 1.10.
For more information about configuring AS numbers, see the Junos Routing
Protocols Configuration Guide.
