[c-nsp] Cisco IIH padding

[Alex K.]

Hello everybody,

Although I have “no hello padding” configured, the adjacency won't come up
until I limit the CLNS MTU on some link in my network (there is an MTU
issue on that link, it's not 1500).

As far as I remember, Cisco IOS implementation of IS-IS will *still send
out first* IIHs padded, never mind I had “no hello padding” *configured*.
On the other hand, it seems like that isn't documented. Can anybody kindly
point out for me (and probably, for the rest of the list) the correct
documentation for that and if this is still relevant for modern IOS/IOS-XE
versions?


 Thank you.
