FS#403 — FS#4481 — bru-1-6k: 10G migration

Attached to Project— Network

Whole Network
CLOSED
100%
The router bru-1-6k (Brussels) is connected on two routers
through 2 10G links. We will reconnect one of the 10G
to switch on rbx-97-99 instead of rbx-99.

The migration is completed.

We had an interruption due to the configuration of the BGP
on the router rbx-97. It has been fixed.

The access to 217.136.92.241 is not for chtix customers
in Brussels.
It is due to the fact that belgacom announce 217.136.64.0/19 AS5432
behind AS6774 (in International) and on the peering with
AS5432 we see 217.136.0.0/16. The rbx-97 only knows
Brussels routes. So it loops.

We will change the configuration between bru-1 and rbx1-97
to avoid making the L3 to rbx-97 and then down
BGP on this router.
