Google Engineer. Dual CCIE #38070. JNCIE-SP #2227
The vast majority of the SP exam is routing. Very little switching is involved. I wanted to create a new INE SPv3 topology, but replace the IOS-XR devices with Juniper M routers. I didn’t want to have to connect the IOS routers to each other via a real switch, rather a virtual one. I did…
This is an ongoing post. Part 1 is over here:http://mellowd.co.uk/ccie/?p=3423 Label values Other than the config I’ve done before, all the other config is left to defaults. Let’s have a look at label allocations. I’ve run wireshark and then captures a ping to each CE. The bottom label is the VPN given by the last…
My first of a series of posts for MPLS interoperability between Cisco’s IOS, Juniper’s Junos, and Brocade’s Netiron code. This post will use the same core I set up before: L3 VPN is one of the more common applications for MPLS. This post will show a very basic three customer site. I’ll leave off all…
While my previous post showed how to create RSVP tunnels between these three providers, I did not mention some of the caveats between these devices. The biggest thing is that even if you hard code paths through the network, the tunnels on IOS will refuse to come up until traffic engineering is actually running on…
I wanted to test inter-vendor MPLS L3VPN compatibility between Brocade, Cisco, and Juniper. The ‘core’ itself will be Junos. In a future post I’ll probably have a random Brocade/Cisco device in the core as well to show how that works. This post will be the basis for a number of future posts on various MPLS…
