M10i is quite aging platform, displaying varying amount of issues. I'd say MX and M120 would be better picks. One particular example comes to mind is inability to pop explicit-null and decreasing IP TTL at the same time, making egress PE disappear from traceroute, when using core-hiding and explicit-null. (PFC3B also suffers from this, but PFC3C with SXH should not, haven't tested though). > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Saku Ytti > Sent: Sunday, August 03, 2008 1:41 AM > To: [email protected] > Subject: Re: [c-nsp] MPLS PE Routers for a Mobile Carrier? > > On (2008-08-02 20:20 +0000), Felix Nkansah wrote: > > > I am working on an MPLS proposal for a mobile carrier (with 2mil+ > > customers). > > > > I need to decide on what routers to use as PE and P for their backhaul > > between 5 sites. > > > > I am torn between proposing the Cisco ASR 1000 OR the Cisco 7600 series as > > PE/P. > > > > Please let me know what your expert opinion is on this matter.
