[NETVIRT-1289] stale entries for dhcp interfaces retained in data-stores when open-stack dhcp is enabled

Fri, 13 Jul 2018 06:18:53 +0000

stale entries for dhcp interfaces retained in prefix-to interface data-store when open-stack dhcp is enabled after deletion of all the configs.

steps

=========

Create Network1 with each Subnet(ipv4 and IPv6)and boot VM.
Create Network2 with each Subnet(ipv4 and IPv6)and boot VM.
Create Router
Associate Subnet to it. --> Check FIB entries Observed
Dissociate subnet from Router --> Check FIB entries removed.
Repeat associate and dissociate multiple time(5 times) and validate data path
Delete all network,port,subnet, Router and check flows and data stores.
Verification has to be done following points.

1. All Config Data stores.

2. All Operational Data stores.

3. FIB Entries.

4. Dump-flows. – > Verify with Dump-flows which was taken before testing

5.Dump-groups.-> . – > Verify with Dump-Groups which was taken before testing
