Peering sessions are reset when you change the router ID of a BGP router. Upon changing the router ID, the system
automatically restarts the BGP instance for the configuration to take effect.
DellEMC# configure terminal
DellEMC(conf)# router bgp 400
DellEMC(conf-router_bgp)# bgp router-id 1.1.1.1
Following is the sample output of show ip bgp ipv4 multicast summary command.

Configuring AS4 Number Representations
Enable one type of AS number representation: ASPLAIN, ASDOT+, or ASDOT.
Term
Description
ASPLAIN
Default method for AS number representation. With the ASPLAIN notation, a 32bit binary AS number is
translated into a decimal value.
ASDOT+ A representation splits the full binary 4-byte AS number into two words of 16 bits separated by a decimal
point (.): <high-order 16 bit value>.<low-order 16 bit value>.
ASDOT A representation combines the ASPLAIN and ASDOT+ representations. AS numbers less than 65536
appear in integer format (asplain); AS numbers equal to or greater than 65536 appear using the decimal
method (asdot+). For example, the AS number 65526 appears as 65526 and the AS number 65546
appears as 1.10.
NOTE: The ASDOT and ASDOT+ representations are supported only with the 4-Byte AS numbers feature. If you do not
implement 4-Byte AS numbers, only ASPLAIN representation is supported.
Only one form of AS number representation is supported at a time. You cannot combine the types of representations within an
AS.
To configure AS4 number representations, use the following commands.
Enable ASPLAIN AS Number representation.
CONFIG-ROUTER-BGP mode
bgp asnotation asplain
NOTE: ASPLAIN is the default method Dell EMC Networking OS uses and does not appear in the configuration display.
Enable ASDOT AS Number representation.
CONFIG-ROUTER-BGP mode
bgp asnotation asdot
Enable ASDOT+ AS Number representation.
CONFIG-ROUTER-BGP mode
bgp asnotation asdot+
The following example shows the bgp asnotation asplain command output.
DellEMC(conf-router_bgp)#bgp asnotation asplain
DellEMC(conf-router_bgp)#sho conf
