PPP Multilink

I wanted to find out a bit more about how to configure and test ppp multilink (ppp over parallel links). It gets a mention in ICND2 but nothing specific on configuration. I’ve encountered it before for ISDN dial-ups from Congo and Zyxel routers so naturally I’m curious to see how it’s done the Cisco way. Multilink ppp balances the traffic equally over the links at layer 2 whilst allowing the layer 3 in each router to treat the parallel links as a single link. Continue reading


CCNA Lab I’ve been slowly progressing through CCNA for a while now, proof that you can teach an old dog new tricks. ICND1 was mainly basic theory and an introduction to Cisco IOS command line – I surprised myself by passing 604-822 at the first attempt.

Here is my lab – a selection of switches and routers. These should allow me to do all the simulations I need for ICND part 2 and maybe beyond…

I’ve learned and implemented some new (to me) concepts from this, although practical applications have not been with Cisco equipment, I’d prefer to call them vendor neutral so far. The most interesting project was converting  a FreeBSD ntp server that used multiple network cards.  I updated this to use 802.1Q tagged vlans using an Allied Telesyn switch.

I’ve even discovered that you can do RIP and OSPF routing in Windows :0
