cisco_xr_show_ospf_database_external

Reference path: 

ttp://platform/cisco_xr_show_ospf_database_external.txt

This template initially designed for use with N2G library to produce network diagrams based on OSPF link state database of Cisco IOS-XR devices.

This template parses external-lsa only out of output produced by "show ospf database external" command.

Caveats:

  • need ttp>=0.7.0, ttp==0.6.0 will not work due to bugs in it

Produces this structure for each input datum/device output:
