2 x 1921 L2TPv3 z podkładem L2tp jako klient do Mikrotik

#1

#1 Post autor: zaber »

Witam
Mam postawiony koncentrator tuneli L2tp, stoi to na Mikrotiku. Na tunelach L2TP mam EoIP i po zmianie softu na ROS7 pojawiły się L2TPv3, okazało się być bardziej stabilnie niż na EOIP więc te MT które mogłem podnieść do OS7 przerobiłem działają i teraz ...

Zapiąłem do MT Cisco 881 tunelem L2TP skonfigurowałem L2TPV3 Xconnect według tutoriali i nie działa. Sam podkład śmiga pinguję połączeniówkę, dostaję się z PC na router po adresacji tunelu L2TP.
Łączył ktoś tych dwóch producentów.
Kombinowałem też z konfiguracją manualną po obu stronach dla L2TPV3 wtedy tunele są UP UP ale ruch nie idzie.
Ostatnio zmieniony 22 sty 2023, 15:48 przez zaber, łącznie zmieniany 1 raz.
A takie tam ...

Przerobiłem połączenie na dwa C1921
Przy połączeniu kablem int C1921-XCONN1 GE0/0 -> C1921-XCONN2 GE0/0 i konfiguracji xconnecta pomiędzy routerami połączenie wstaje i ruch śmiga więc myślę że licencyjnie i IOS jest dobre.
Przechodzę dalej do docelowego ustawienia i routery zostają spięte ze sobą do serwera L2tp który jest wystawiony na Mikrotiku
L2tp w routerach cisco łączy się za pośrednictwem Virtual-PPP, wszystko się zapina, ruch śmiga, zestawiłem też testowo BGP do MT na interfejsach loopback w Cisco.
Z jednego routera Cisco 1921 pinguję adres połączeniowy drugiego Cisco 1921 jak i Loopback-i po BGP.
Już nie wiem co może być że połączenie xconnect pomiędzy routerami się nie zestawia
Docelowo chciał bym zestawić Xconnect (L2tpv3) do Mikrotik-a ale to później.

Moje konfiguracje na MT oraz na routerach cisco :
