hi,
a decision is made here so i just added this md5 stuff for ospf with these
changes:
https://github.com/mc36/freeRouter/commit/908ef281b3e26891c94ac0a1bfc09ce6f9765d46
now some test cases need to cover the functionality then i'll proceed to isis
md5...
regards,
cs

Hi Csaba,

Thanks for the links. I am using a Juniper at the other end. The ISIS group
configuration contains the md5 config for the interfaces, but you can
override the global config by explicitly configuring the interfaces under the
protocol ISIS.
So the following works fine.
ekenny@edge1-testlab> show configuration protocols isis interface ge-1/1/8.0
hello-padding disable;
level 1 disable;
level 2 {
hello-authentication-key "$9removed"; ## SECRET-DATA
hello-authentication-type simple;
}
ekenny@edge1-testlab>

edge5-testlab#show running-config ethernet3
interface ethernet3
description "Link to edge1-testlab"
vrf forwarding isisvrf
ipv4 address 192.168.1.1 255.255.255.254
router isis4 1 enable
router isis4 1 circuit level2
router isis4 1 password $v10$removed==
no shutdown
no log-link-change
exit

Thank you for your help.

Regards
Eoin

hi,
at the moment, freerouter can only do cleartext authentication on interface
or lsp level:
http://sources.nop.hu/cfg/intop2-isis08.tst
http://sources.nop.hu/cfg/intop2-isis11.tst
in both tests, r1 is freerouter and r2 is xrv9k...

cs

Hi all,

I maybe missing something obvious but I could not see how to configure MD5
hello authentication for ISIS on freerouter. Any suggestions or points would
be appreciated.

Thanks
Eoin
