If you unconfigure the bgp redistribute-internal command, use the clear ip BGP * command to clear all BGP
sessions.
Enabling Additional Paths
The add-path feature is disabled by default.
NOTE: Dell EMC Networking OS recommends not using multipath and add path simultaneously in a route reflector.
To allow multiple paths sent to peers, use the following commands.
1. Allow the advertisement of multiple paths for the same address prefix without the new paths replacing any previous ones.
CONFIG-ROUTER-BGP mode
bgp add-path [both|received|send] path-count count
The range is from 2 to 64.
2. Allow the specified neighbor/peer group to send/ receive multiple path advertisements.
CONFIG-ROUTER-BGP mode
neighbor add-path
NOTE:
The path-count parameter controls the number of paths that are advertised, not the number of paths that are
received.
Configuring IP Community Lists
Within Dell EMC Networking OS, you have multiple methods of manipulating routing attributes.
One attribute you can manipulate is the COMMUNITY attribute. This attribute is an optional attribute that is defined for a group
of destinations. In Dell EMC Networking OS, you can assign a COMMUNITY attribute to BGP routers by using an IP community
list. After you create an IP community list, you can apply routing decisions to all routers meeting the criteria in the IP community
list.
