Internet connectivity issues due to proliferation of BGP full-view

I will be brief.
The BGP full-view size approached the 512K mark, which began to lead to problems with older routers. At least Cisco 7600, Cisco ASR 9000, Cisco ASR 1000 and Cisco Catalyst 6500 are supported.
Access problems arose , in particular, for Comcast, LastPass and eBay, and in some places Russian resources were not available.
As a workaround , an increase in the IPv4 routing table due to the IPv6 table is proposed .

As the number of entries approaches 512K, more and more affected routers will be affected. Overcoming the 512K mark is expected next week.
