##################### Summary #########

Prob1) Do I need to create docker networks

create docker networks

docker network create net1
docker network create net2

Prob2) cEOS doesnt show multiple interfaces

[hellt]

Hi,
try and change ceos interfaces from

• e1 to eth1
• e2 to eth2 and so forth

[dharmbhai]

Hi @hellt
Some good news:
I did console to Leaf2 and there Interfaces and LLDP info is accurate, only the Leaf1 is showing inaccurate info
Similarly, Leaf3 is showing inaccurate info, and leaf4 is inaccurate
The pattern is not clear.

[hellt]

I can confirm that the same errors appear on my machine using your topology
Will have a look

[hellt]

ok, funny, can you

1. destroy the lab first with containerlab des -t <filename>
2. remove the - from the lab name on line1 and make it like ceosclos01 and retry?

[hellt]

@dharmbhai the fix for that issue is in #359
for now you can just eliminate the dash in the lab' name, but in next release this will be fixed
Thanks for reporting

[dharmbhai]

Hi @hellt
I confirm, after removing the - in the 1st line, everything works perfectly fine.
