The range is from 2 to 64.2. Allow the specified neighbor/peer group to send/ receive multiple path advertisements.CONFIG-ROUTER-BGP modeneighbor add-pathNOTE: The path-count parameter controls the number of paths that are advertised, not the number of paths that arereceived.Configuring IP Community ListsWithin Dell 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 ofdestinations. In Dell Networking OS, you can assign a COMMUNITY attribute to BGP routers by using an IP community list. After youcreate an IP community list, you can apply routing decisions to all routers meeting the criteria in the IP community list.IETF RFC 1997 defines the COMMUNITY attribute and the predefined communities of INTERNET, NO_EXPORT_SUBCONFED,NO_ADVERTISE, and NO_EXPORT. All BGP routes belong to the INTERNET community. In the RFC, the other communities aredefined as follows:• All routes with the NO_EXPORT_SUBCONFED (0xFFFFFF03) community attribute are not sent to CONFED-EBGP or EBGPpeers, but are sent to IBGP peers within CONFED-SUB-AS.• All routes with the NO_ADVERTISE (0xFFFFFF02) community attribute must not be advertised.• All routes with the NO_EXPORT (0xFFFFFF01) community attribute must not be advertised outside a BGP confederationboundary, but are sent to CONFED-EBGP and IBGP peers.Dell Networking OS also supports BGP Extended Communities as described in RFC 4360 — BGP Extended Communities Attribute.To configure an IP community list, use these commands.1. Create a community list and enter COMMUNITY-LIST mode.CONFIGURATION modeip community-list community-list-name2. Configure a community list by denying or permitting specific community numbers or types of community.CONFIG-COMMUNITYLIST mode{deny | permit} {community-number | local-AS | no-advertise | no-export | quote-regexpregular-expression-list | regexp regular-expression}• community-number: use AA:NN format where AA is the AS number (2 Bytes or 4 Bytes) and NN is a value specific tothat autonomous system.• local-AS: routes with the COMMUNITY attribute of NO_EXPORT_SUBCONFED.• no-advertise: routes with the COMMUNITY attribute of NO_ADVERTISE.• no-export: routes with the COMMUNITY attribute of NO_EXPORT.• quote-regexp: then any number of regular expressions. The software applies all regular expressions in the list.• regexp: then a regular expression.Example of the show ip community-lists CommandTo view the configuration, use the show config command in CONFIGURATION COMMUNITY-LIST or CONFIGURATIONEXTCOMMUNITY LIST mode or the show ip {community-lists | extcommunity-list} command in EXEC Privilegemode.Dell#show ip community-listsip community-list standard 1deny 701:20deny 702:20deny 703:20deny 704:20Border Gateway Protocol IPv4 (BGPv4) 201
