В mpls-сети крупного ISP, в процессе роста, неизбежно возникает проблема масштабирования по числу igp и vpnv4 маршрутов. Однако, наши глубокоуважаемые вендоры (Cisco, Huawei... etc.) заботятся о нас :)
В частности, на ciscoexpo`12 была неплохая сессия по Unified MPLS . Аналогичные решения есть и у Huawei, отличия в незначительных деталях, например, Cisco использует level 1- level 2 is-is, a Huawei - отдельные igp-процессы c редистрибьюцией. Для нас удобнее второй вариант, т.к. существующая сеть организована как единый is-is level 2 only домен.
Србственно, захотелось пощупать это руками в динамипсе. Между СЕ1 и СЕ2 организован L2vpn+L3vpn, на СR1 и СR2 для vrf TEST осуществляется аггрегация маршрутов в сети /24, между СR1 и СR2 фильтруются все vpnv4 маршруты длиннее /24.
Конфигурации динамипса (GNS3) и роутеров под катом.
