IS-IS is not an IP protocol, it’s a layer 2 protocol, meaning it has its own Ethertype.

First, i registered ISIS in tap inject, by adding the following line: ip4_register_protocol (IP_PROTOCOL_ISIS, im->tx_node_index); in tap_inject_enable (void) function located at vppsb/router/router/tap_inject.c file! However, the problem remained unsolved. Is there a special issue related to is-is that i should know? Anyone can help me? Regards, Gulakh
