What is a disadvantage to multihoming and accepting only a default route from each ISP?
- Because of load balancing between ISPs, suboptimal routing may occur.
- Because routers will select the edge router based on the IGP metric, suboptimal routing may occur.
- Because routing loops within the IGP routing domain may occur, only a single ISP connection can be used.
- Because no more than one default route can be advertised into the IGP routing domain, only a single ISP connection can be used.
