[dev] Support for SR TE in FRR

[olivier.dugeon at orange.com]

Hello Shuvro,

Your setup is almost complete. What is missing is the interface configuration.

For each interface you would advertise TE information through the routing protocol, you need to add 'link-param' statement. Please refer to this section in FRR documentation: http://docs.frrouting.org/en/latest/zebra.html#link-parameters-commands  You also find some complete example for OSPF here: http://docs.frrouting.org/en/latest/ospfd.html#ospf-configuration-examples

Let me know if you have any trouble

Regards

Olivier
