Folks,
This issue was discussed some time ago and we didn't officially resolve
it on the list.
Basavaraj is suggesting that the hard limit of 1800 seconds is
restrictive to some deployments (cellular) and suggests that we increase
it.
Here is how it is currently defined:
MaxRtrAdvInterval
The maximum time allowed between sending
unsolicited multicast Router Advertisements from
the interface, in seconds. MUST be no less than 4
seconds and no greater than 1800 seconds.
Default: 600 seconds
Realistically there are two possible options to handle this:
1. Accept the issue: Increase the value of the MaxRtrAdvInterval. It
seems that in order to do this in a backward compatible way, we can't
increase it beyond 2999 seconds. That's because the default value for
the AdvDefaultLifetime is 3 * MaxRtrAdvInterval and it must be < 9000
seconds.
2. Reject the issue.
Please let me know if the suggestions above are flawed or if you have
another option to include. Otherwise, please express your opinions as to
whether we should choose 1) or 2) above.
Personally I have no problem with 1).
