SUMMARY

Get an exception trying to parse the above with the arista_show_ip_route template
textfsm.parser.TextFSMError: State Error raised. Rule Line: 23. Input Line:  C        162.220.49.128/31 is directly connected, Tunnel11, Static Interface GRE tunnel index 11, dst 184.170.244.12, src 216.201.90.212
##### STEPS TO REPRODUCE

show IP route <prefix> longer-prefixes and have a gre tunnel route in the output

EXPECTED RESULTS

Parsed output.

ACTUAL RESULTS

textfsm.parser.TextFSMError: State Error raised. Rule Line: 23. Input Line:  C        162.220.49.128/31 is directly connected, Tunnel11, Static Interface GRE tunnel index 11, dst 184.170.244.12, src 216.201.90.212

[itdependsnetworks]

I have updated the comment to better format the output.

[diepes]

PR #843 - nexthop ip/int changed to List, not parsing details in tunnel nexthop, just extracting it.

[FragmentedPacket]

Fixed via #843, not confirmed by user.
