Attribute Name
The tunneling protocol(s) to be used (in the case of a tunnel initiator)
or the tunneling protocol in use (in the case of a tunnel terminator).
This attribute is mandatory on LAC Access-Accept and needs to be
L2TP. The same attribute is included on LNS in the Access-Request
and Acct-Request if the CLI RADIUS policy include-radius-attribute
tunnel-server-attrs is enabled on 7x50 LNS. For L2TP Tunnel/Link
Accounting this attribute is always included on LAC and LNS.
The transport medium to use when creating a tunnel for those
protocols (such as L2TP) that can operate over multiple transports.
This attribute is mandatory on LAC Access-Accept and needs to be
IP or 'IPv4.The same attribute is included on LNS in the Access-
Request and Acct-Request if the CLI RADIUS policy include-
radius-attribute tunnel-server-attrs is enabled on 7x50 LNS. For
L2TP Tunnel/Link Accounting this attribute is always included on
LAC and LNS.
The dotted-decimal IP address of the initiator end of the tunnel. Pre-
configured values are used when attribute is omitted (configure
router/service vprn <service-id> l2tp local-address). If omitted in
Access Accept on LAC and no local-address configured, then the
address is taken from the interface with name system. This attribute
is included on LNS in the Access-Request and Acct-Request only if
the CLI RADIUS policy include-radius-attribute tunnel-server-attrs
is enabled on 7x50 LNS. For L2TP Tunnel/Link Accounting this
attribute is always included on LAC and LNS as untagged.
The dotted-decimal IP address of the server end of the tunnel is also
on the LAC the dest-ip for all L2TP packets for that tunnel.
To support more than 31 tunnels in a single Radius Access-Accept
message, multiple Tunnel-Server-Endpoint attributes with the same
tag can be inserted. All tunnels specified by Tunnel-Sever-Endpoint
attributes with a given tag will use the tunnel parameters specified by
the other Tunnel attributes having the same tag value.
