SUMMARY

cisco_xr_show_ip_route.template currently does not account for non-hh:mm:ss uptime formats, such as '1y03w'
cisco_xr_show_ip_route.template currently does not account for protocol sub-type support, such as 'D EX'
I have a working template if you prefer I submit a pull request for this.

STEPS TO REPRODUCE

Use the above show ip route output as 'sh_ip_route.txt'.
Use the following script as 'check.py':

import textfsm

with open('sh_ip_route.txt', 'r') as input_file:
    iproute_raw = input_file.read()

with open('./templates/cisco_xr_show_ip_route.template', 'r') as template_file:
    re_table = textfsm.TextFSM(template_file)
    fsm_results = re_table.ParseText(iproute_raw)

print(fsm_results)

Run python check.py

EXPECTED RESULTS

Receive a list of 2 lists corresponding to the 2 routes in the show ip route output.

ACTUAL RESULTS
