IPv6 address in full and CIDR notation is perceived as different ip-addresses #7

Closed xivamar closed 7 years ago

xivamar commented 8 years ago

Problem Description:

We can configure 2 same active static routes (in normal notation and in CIDR notation).

OpenSwitch version:

OpenSwitch 0.4.0 (Build: appliance-ops-0.4.0-master-20160823125534-dev)

Test Topology:

      DUT3 
     /    \
 DUT2 --- DUT4
    \      /
      DUT1

Steps to reproduce the problem (see attached file):

  1. Configure ipv6 addresses on each DUTs as in attached file.
  2. Add static route with 2002:0:0:0:0:0:6500:1 nexthop to 2002::6600:8/126 network on DUT1.
  3. Try to add static route with 2002::6500:1 nexthop to 2002::6600:8/126 network on DUT1. - NOK: Error messageNexthop already existsshould be returned.
  4. Check config via show running-config and show rib. - NOK: Config contains 2 same static routes.

Two active static routes with identical nexthop .txt

Also same problem is present in BGP: if BGP neighbors were configured with IPv6 address in full notation , session between neighbors will not Established.
