The peer-group-name specifies all neighbors in a specific peer group. The as-num parameter specifies
all neighbors within the specified AS. After choosing one mandatory parameter, you can choose an
optional parameter.
The soft in and soft out parameters determine whether to refresh the routes received from the
neighbor or the routes sent to the neighbor. If you do not specify in or out , the device performs a soft
refresh in both options:
• soft in performs one of the following actions on inbound routes, according to other configuration
settings:
‐ If you enabled soft reconfiguration for the neighbor or peer group, soft in updates the routes
by comparing the route policies against the route updates that the device has stored. Soft
reconfiguration does not request additional updates from the neighbor or otherwise affect
the session with the neighbor.
‐ If you did not enable soft reconfiguration, soft in requests the entire BGP4 route table on
the neighbor (Adj-RIB-Out), then applies the filters to add, change, or exclude routes.
‐ If a neighbor does not support dynamic refresh, soft in resets the neighbor session.
• soft out updates all outbound routes and then sends the entire BGP4 route table for the device (Adj-
RIB-Out) to the neighbor after the device changes or excludes the routes affected by the filters.
• The soft-outbound parameter updates all outbound routes by applying the new or changed filters,
but sends only the existing routes affected by the new or changed filters to the neighbor.
NOTE
Use soft-outbound only if the outbound policy is changed. The soft-outbound parameter updates all
outbound routes by applying the new or changed filters. However, the device sends to the neighbor only
the existing routes that are affected by the new or changed filters.The soft out parameter updates all
outbound routes and then sends the entire BGP4 route table on the device to the neighbor after the
device changes or excludes the routes affected by the filters.
AS4 notation
A AS4 can appear in either a plain or a dot notation format in the output of show commands. To select
one of these formats, specify the format before entering the show command. This section defines these
formats and describes how to select a format. The following notations are currently supported:
• With the default asplain , the ASN is a decimal integer in the range 1 - 4294967295.
• With asdot +, all ASNs are two integer values joined by a period character in the following format:
.
Using the asdot+ notation, an autonomous system number of value 65526 is represented as the string
"0.65526," and an autonomous system number of value 65546 is represented as the string "1.10."
• With asdot, an ASN less than 65536 uses the asplain notation (and represents autonomous system
number values equal to or greater than 65536 using the asdot+ notation). Using the asdot notation,
ASN 65526 is represented as the string "65526," and ASN 65546 is represented as the string "1.10".
NOTE
You can enter autonomous system numbers in any format. However, if you want the asdot or the asdot
+ format to appear in the output of a show command, you must specify these in the CLI.
