# Network Lab

Add a TFTP server section to Linux document
Correct Main document to include erasing flash if insufficient space for new image

set password in pod example configs to as#as#
use enable secret

Add show ip bgp neighbor <neighbor> routes advertised-routes to troubleshooting
if not already present


BGP backbone solution:
 Use BGP instead of RIP as primary method to adv routes to lab backbone
 Use distribute list on backbone to prevent transit
 Note that if one router is not running BGP, but has default route, can ping all
 other routers through backbone.

BGP Default routes:
 Must use BGP to advertise default routes to pod since isis can't
 Default routes can be distributed with neighbor x.x.x.x default-information
 Must set bgp max-path 2 to see 2 paths on backbone router
 Must set max-path ibgp 2 to see 2 def routes on pod routers

BGP holdtime is 180 secs (3 min), keepalive is 1 min
can set per neighbor with neighbor <ip> timers 20 60

ISIS
  default_info orig only works on L2 (include this in case fixed by publish time)
  uses Attached (ATT) bit to create default routes in L1 but only works if doing multi-area
  isisd will die when eth interfaces are shutdown
  ignore-lsp-errors is on by default!
  should set isis priority on int to 0 to prevent DIS elect


<<<remember to save BGP method>>>
