RADIUS IETF Attributes 22(Framed-Route):

String that provides routing information to be configured for the user on the NAS in the format:

<addr>[/<maskLen>] [<nexthop> [<cost>]] [tag <tagValue>] [distance <distValue>]

For example:

Framed-Route = "192.168.0.0/24 192.168.0.1"

Other vendor BRAS may use IETF Attributes 22 in different format.

If MX has not used this IETF Attributes, we can set below knob to ignore this attribute.

#set access profile radius-profile radius attributes ignore standard-attribute 22
