Im looking for some advice. We have a private mpls network built using poi t to point links. Routers are Cisco isr 4000 series.
All links are currently <1Gb. I have a requirement to uplift this to 10Gb. Our standard is to go ASRs or ISRs. If I want >3 x 10Gb ports I would essentially be forced to get ASR 1001-HX if I want to continue using routers.
My main question is: what is the main thing that would stop you doing mpls on a Cisco cat 9k? It has the port density I need, the throughout, does vpnv4 and mpls.
But I need to have the justification as tm why we need routers vs l3 switches... What's the general gap between them here?
