system ignores all other instances. Note that the next hop must be directly connected otherwise the packets will be
discarded.
General:
Format:
adc-avpair = "route:nip-pipe-next-hop=<Next-hop IP address>",
Example:
adc-avpair = "route:nip-pipe-next-hop=192.168.1.23",
route:advertise-protocol attribute
The route:advertise-protocol sub-attribute defines the routing protocol to be use to advertise the session IP address.
The system when receiving this attribute advertises the session IP address via the received protocol regardless to
the system default routing definition.
General:
Format:
adc-avpair = "route:advertise-protocol=<ripv2 | ospf>",
Example:
adc-avpair = "route:advertise-protocol=ospf
route:forward-addr attribute
The route:forward-addr sub-attribute defines the forwarding address. This address is indicating that packets for the
external destination (user IP address) should be forwarded to the specified forwarding address by the downstream
router (not to the system). This attribute may be received dynamically during the session lifetime – It supports
hierarchy operation mode. It may be included once in access accept messages, and the system ignores all other
instances. This attribute is valid only when route:advertise-protocol attribute is defined, otherwise the system should
ignore it. The forward-addr default value is 0.0.0.0. This attribute is supported only for OSPF advertising protocol.
Note: The attribute is relevant only for native IP traffic over Ethernet.
