BGP 1385
For this reason, if a route reflector client has an outbound neighbor route-
map configured, the set statements in the route map are ignored.
VRF Support
Dell EMC Networking switches that support BGP and VRFs also support
BGP in conjunction with OSPF or statically routed VRFs. When configured
in a VRF, the single instance of BGP runs independent sessions to neighbors
in the VRF and forwards independently.
BGP Neighbor Configuration
Dell EMC Networking BGP supports configuration of eBGP neighbors that
are not directly connected using the ebgp-multihop parameter to the
neighbor command. Multi-hop is supported only for eBGP configurations
where the neighbor has a different AS number. Dell EMC Networking iBGP
requires neighbors to be directly connected.
Dell EMC Networking BGP also supports auto-detection of a neighbor's IPv6
link local address. The BGP neighbor must be directly connected and the link
must be configured to use IPv6 addressing.
Extended Communities
Dell EMC Networking BGP supports standard extended communities as
defined in RFC 4360. Dell EMC Networking BGP supports extended
community lists for matching routes based on the extended community and
supports matching and setting of extended communities in route maps. It
also supports selective export and import of routes using export and import
maps.
The extended community attribute provides a mechanism for labeling routes
carried in BGP-4. These labels are then used to control the distribution of
routes among VRFs. The extended community attribute is sent by BGP when
configured in the default VRF only, i.e., as part of an MP-BGP configuration.
A BGP NLRI can carry both standard and extended community attributes
and it can also carry multiple community attributes through the use of the
additive keyword in the case of standard communities, and through the use of
route-maps when exporting the VRF routes in the case of extended
communities.
