"cisco как vpn client"  +/
Сообщение от rus73leon email(ok) on 31-Авг-15, 15:15 
Hi all !

Есть задачка,
нужно поднять vpn соединение через интернет с cisco роутера до удаленного филиала (mikrotik)

первоначально был cisco 871 12.4(15), vpn поднял:
service internal

l2tp-class leon
receive-window 256

pseudowire-class class1
encapsulation l2tpv2
protocol l2tpv2 leon
ip local interface Dialer0

interface Virtual-PPP1
ip address negotiated
no ip proxy-arp
ip mtu 1450
ip virtual-reassembly
ip tcp adjust-mss 1410
no peer neighbor-route
no cdp enable
ppp pfc local request
ppp authentication chap ms-chap ms-chap-v2 callin
ppp chap hostname ppp_leon2
ppp chap password 7 040A59555B74
pseudowire x.x.x.x 10 pw-class class1

все работает.

сейчас возникла необходимость замены оборудования на cisco 1921 15.4(3)
указаннй выше конфиг уже не работает (((
не могу понять в чем дело. постоянно "line protocol is down"

gw-01#sho int virtual-ppp1
Virtual-PPP1 is up, line protocol is down
  Hardware is Virtual PPP interface
  Internet address will be negotiated using IPCP
  MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100000 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation PPP, LCP Closing, loopback not set
  Keepalive set (10 sec)
  DTR is pulsed for 1 seconds on reset
  Last input 00:02:24, output never, output hang never
  Last clearing of "show interface" counters 3d00h
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     584 packets input, 8296 bytes, 0 no buffer
     Received 0 broadcasts (0 IP multicasts)
     0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     373 packets output, 7018 bytes, 0 underruns
     0 output errors, 0 collisions, 0 interface resets
     0 unknown protocol drops
     0 output buffer failures, 0 output buffers swapped out
     0 carrier transitions

Вообще, нормальные люди для целей site-to-site vpn используют ipsec или gre over ipsec.
А по теме, выкладывайте debug ppp negotiation для начала.

можете подсказать как в данной ситуации с интерфейсом virtual-ppp прикрутить ipsec ?
