[BGPCEP-802] RT-Constrain Default route serializing Error

Wed, 27 Jun 2018 16:09:31 +0000

Overview: Configure app peer and internal peer with route-target-constrain. Send route via internal peer with play.py Error happening when parsing incoming message in odl.

Hex is gained by sending the route to app-peer and catching the route on advertisement from the odl to peer. So the mistake could be in route config, Or route serializer or parser.

When sending route-target-constrain-default-route before I had:

ffffffffffffffffffffffffffffffff0031020000001a4001010040020040050400000064800e0900018404c714a62900

Now with addition of origin-as it is:

ffffffffffffffffffffffffffffffff0036020000001f4001010040020040050400000064800e0e00018404c714a62900600000ff98

Steps to reproduce:

configure app-peer and int-peer.
```
./configure.py
```
start play.py (new version from attachments) with
```
sudo ./start_play.sh
```
Send route via play.py with
```
./hex_default.py
```

Type default fails with:
