Cisco Virtual Lab hasn’t been update since March 2018.   I decided to put the $200 for it towards other certs that I can get faster.   I asked Karlo to contact me when they finally upgrade it.   

I have taken all my simulations and moved them into the menu at the top.  I separated them into categories to clean up the page.  Click on Cisco VIRL Simulations in menu.

sudo service redis-server restart : my VIRL needs a manual restart of redis.

Internal data structure resulting from the First Method: six CIDR blocks comprising a pool of 101

2001:DB8::64 / 126 (100-103, 4 addresses)
2001:DB8::68 / 125 (104-111, 8 addresses)
2001:DB8::70 / 124 (112-127, 16 addresses)
2001:DB8::80 / 122 (128-191, 64 addresses)
2001:DB8::C0 / 125 (192-199, 8 addresses)
2001:DB8::C8 / 128 (200, only 1 address)

64 = (6 * 16^1 ) + ( 4 * 16^0 ) = 100
C0 = (12 * 16^1 ) + ( 0 ) = 192

Internal data structure resulting from the Second Method: one CIDR block, one pool of 256

The auto-negotiation option is only effective when using the GBIC media, it is used to enable the IEEE 802.1z Gigabit Ethernet (1000 Mbps) auto-negotiation protocol, thus the auto-negotiation feature is not supported when using the rj-45 media type (which is your case) and will be ignored if enabled, more over this feature has no relation with slowness or delay over the interface.
