The code concerned however is explicitly /not/ being distributed under

other things.
Because Debian distributes[1] FRR in compliance with the terms of the
GPL, and the terms of the license of the subparts of FRR are
compatible with the GPL, Debian is not in violation of the terms of
the GPL.
The GPL stipulates that the distributor must "appropriately publish on
each copy an appropriate copyright notice".
FRR deliberately do not so on a number of files, in the ldpd and babeld
directories most notably, even where those files do prominently feature
notice of another licence (a weaker one lacking the requirements of the
GPL).
This is very deliberate, as FRR denies the applicablility of the GPL to
those files, even though these files are dependent on the GPL source
code for function and comprehension and these files are derived works of
the GPL source code, according to legal advice. The FRR project - by
their own words - are not distributing this code under the GPL,
manifested no least by their refusal to comply with the notification
requirement of the GPL.
Non-compliance with conditions stipulated by the GPL licence, on code
that may only be distributed in accordance with the GPL licence, is an
infringement of copyright.
The termination clause of the GPL applies to entities who are
redistributing FRR not to the code base in general; as Debian
redistributes in compliance with the GPL (and presumably the FRR
project on github does as well), Debian hasn't activated GPL-2 ยง4.
The FRR project, and associated entities (such as Cumulus Networks, Big
Switch Networks, 6WIND, LAbN Consulting, Orange Telecom, the Linux
Foundation) have no GPL licence for this code-base.
The Debian project can not magically grant itself a GPL licence for this
infringing code, when the FRR project have none to give.
