RE: Cisco features on Juniper routers/switches

While we are on the subject of interoperability, sometimes there are things
that a vendor doesn't even do very well with itself. Interoperability is a
challenge even within the "family".

Just because you buy all cisco doesn't mean that all your cisco stuff will
play nice with other cisco.

Then when you get into differences like IOS and IOS XR (both cisco) then
there are definite differences there too.

I'm reminded of turning up some MPLS L2VPN BGP Auto-discovered address
families between CISCO me3600 and CISCO asr9k.... neighbor sessions just
bounced/flap over and over..... turns out there is a interoperability tweak
apparently cisco had to do just to get that to interoperate at the neighbor
level. (ios must have "neighbor x.x.x.x prefix-length-size 2" to interop
with ios xr l2vpn vpls af)

So vendors not only have to work out interop issues with other vendors, they
have to work out interop issues with themselves first.

To add what Scott has said,

I am using HP MSR routers with GRE over IPSec configuration. They are
working perfectly fine with Cisco being the hub.

Also i have found MSR to be great alternative to Cisco/Juniper for routing
perspective. Found all the features that typically are required in large
branch setup.

To many's surprise, MSR supports EAA, similar to EEM. Even the syntax is
similar lolz. Its good to try new things that are so promising.
