Deny - Dell Z9500 Command Reference Manual

BGP Extended Communities (RFC 4360)
BGP Extended Communities, as defined in RFC 4360, is an optional transitive BGP attribute.
BGP Extended Communities provides two major advantages over Standard Communities:
• The range is extended from 4-octet (AA:NN) to 8-octet (Type:Value) to provide enough number
communities.
• Communities are structured using a new "Type" field (1 or 2-octets), allowing you to provide granular
control/filter routing information based on the type of extended communities.

deny

To reject (deny) from the two types of extended communities, route origin (rt) or site-of-origin (soo), use
