bgp add-path Allow the advertisement of multiple paths for the same address prefix without the new paths replacing any previous ones. C9000 Series Syntax Parameters bgp add-path [send | receive | both] path-count send receive both path-count Enter the keyword send to indicate that the system sends multiple paths to peers. Enter the keyword receive to indicate that the system accepts multiple paths from peers. Enter the keyword both to indicate that the system sends and accepts multiple paths from peers. (OPTIONAL) Enter the number paths supported. The range is from 2 to 64. Defaults Command Modes Disabled • ROUTER BGP • ROUTER BGP-address-family Command History This guide is platform-specific. For command information about other platforms, refer to the relevant Dell Networking OS Command Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version 9.9(0.0) 9.2(1.0) 8.3.19.0 8.3.11.0 8.3.8.0 Description Introduced on the C9010. Introduced on the Z9500. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Related Commands neighbor add-path - specifies that this neighbor/peer group can send/receive multiple path advertisements. bgp always-compare-med Allows you to enable comparison of the MULTI_EXIT_DISC (MED) attributes in the paths from different external ASs. C9000 Series Syntax bgp always-compare-med To disable comparison of MED, enter no bgp always-compare-med. 356 Border Gateway Protocol
