Appendix A: SG-1Vendor-Specific Attributes

system ignores all other instances. Note that the next hop must be directly connected otherwise the packets will be discarded.

Note: The attribute is relevant only for native IP traffic over Ethernet.

General:

Operation Mode:

Access-Accept message

 

Service-Accept message

Vendor-type:

72

Vendor-length =

2 + attribute length + (1-15)

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:

Operation Mode:

Access-Accept message

 

Service-Accept message

Vendor-type:

73

Vendor-length =

4-5 + attribute length

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.
