While a<br>> different number of routes might work, it will not be a supported or<br>> tested combination.<br>> <br>> For CER:<br>> 256K IPv4 routes + 128K IPv6<br>> 448K IPv4 + 64K IPv6<br>> 512K IPv4 + 0 IPv6<br>> <br>> For CER-RT:<br>> 1.5M IPv4 + 512K IPv6<br>> <br>> "Internet route mix" is used to indicate that we are using a mix of prefix<br>> lengths.
