Layer 3 Routing Commands 1309
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router)#neighbor 10.130.14.55 remove-private-as
neighbor rfc5549-support
Use the neighbor rfc5549-support command to enable advertisement of IPv4
routes over IPv6 next hops selectively to an external BGP IPv6 peer. To
disable advertisement of these routes, use the no form of this command.
Syntax
neighbor { ipv6-address | autodetect interface interface-name } rfc5549-
support
no neighbor {
ipv6-address | autodetect interface interface-name } rfc5549-
support
• ipv6-address — The neighbor’s IPv6 address.
• autodetect interface
interface-name — The routing interface on which the
neighbor’s link local IPv6 address is auto detected.
Default Configuration
RFC 5549 support is enabled by default for all neighbors.
Command Mode
BGP Router Configuration mode, IPv4 Address Family Configuration mode
User Guidelines
This command can only be applied to external BGP peers via a single hop.
The Next Hop Address advertised for the IPv4 prefixes consists of the link-
local IPv6 address and the global IPv6 address (if configured on the interface).
When the Extended Next Hop Encoding capability is not received from a
neighbor, Dell Networking does not advertise the RFC 5549 routes to the
neighbor. The Dell Networking solution is interoperable with routers that do
not support RFC 5549.
