```
##### SUMMARY
A customer reported that upon login ixp manager, ixp manager shows errors.
The "Your Top Peers" table breaks while generating the links to the p2p statistics pages.

We think that the code  

`[ 'srcVli' => $t->c->virtualInterfaces[0]->vlanInterfaces[0]->id,
                                         'dstVli' => $p2p->peer->virtualInterfaces[0]->vlanInterfaces[0]->id ]`

is to blame as virtualInterfaces[0] is not guaranteed to be an interface used for peering.

We have a customer with a reseller uplink port and peering, where the reseller uplink port was created prior to the creation of the peering interface (reseller uplink port virtualinterface has a lower database ID than the virtual interface that has peering).

To temporarily fix the issue we have altered the code as follows:
`[ 'srcVli' => $t->c->virtualInterfaces[ $t->c->abbreviatedName == '<affected_customer>' ? 1 : 0]->vlanInterfaces[0]->id,
'dstVli' => $p2p->peer->virtualInterfaces[ ($t->ee( $p2p->peer->abbreviatedName ) == '<affected_customer>') ? 1 : 0 ]->vlanInterfaces[0]->id ]`
which will use virtualInterface at index 1 when rendering the link containing the affected customer.

##### STEPS TO REPRODUCE

create a customer, create the reseller uplink port first, then create a peering port.

##### EXPECTED RESULTS
 
A "Your Top Peers" table without errors.

##### ACTUAL RESULTS

A broken "Your Top Peers" table.
##### IMPORTANCE

We are affected in production. We have identified at least one customer that is affected from the "Your Top Peers" getting rendered with issues when they are on said table for other customers.
