Cisco ASR Routers
Use Cases and Deployment Scope
This router can be used as the Internet edge router peering with BGP. We also use this router to establish site to site VPN to external business vendors. This enable us to have network connectivity with the Internet and with external business partners.
Pros
- To establish connection with Internet Service Provider.
- To establish site to site VPN connections with external partners.
- Virtualize the router so we can handle different network segmentations.
Cons
- Terminate Direct Internet Access connection with ISP. Run BGP routing to affect inbound and outbound Internet traffic.
- Establish IPSec VPN connections to external partner. Run BGP routing to affect inbound and outbound traffic with different partner networks.
- Using the VRF configuration to virtual the router to different network segments. This enables us to handle traffic to different partners independently.
Return on Investment
- The router virtualization allows us to use single hardware to support different use-cases the same time, thus saving hardware investment.
- The technical support from Cisco is very strong and is willing to advise on different configuration options to address the requirement.
- Cisco equipment is more expensive than other router vendors, and the support cost isn't cheap either.
