zebra: Fix for route node having no tracking NHT
Topology:
IXIA-----(ens192)FRR(ens224)------iXIA
Configuration:
1. Create 8 sub-interfaces on ens192 under Default VRF and configure 8
EBGP session between FRR and IXIA.
2. Create 1000 sub-interfaces on ens224 under Default VRF and configure
1000 EBGP session between FRR and IXIA.
3. 2M prefixes distributed from Left side Ixia each with 8 ECMP path.
4. So in total, there are 2M prefixes * 8 ECMP = 16M prefixes entries
in RIB and FIB.
Issue:
Shut ens192 and ens224, this is taking 1hr 15 mins to clean up the routes.
Root Cause:
In the case of route deletion, if the particular route node is having
nht count = 0, we are going to the parent and doing nht evaluation,
which is not needed.
Fix:
If the deleted the route node is having nht count > 0, then do a nht
evaluation on the parent node.
Shut ens192 and ens224, it is taking 1 min to clean up the routes
with the fix.
