+==== Remove the packet filters from the previous examples ====
+We need IS-IS and BGP to work for the remainder of the lab, so we will remove the packet filters we installed in the previous exercise. Simply go to the interfaces where you defined the “traffic-filter” commands and remove those. Also delete the “ipv6 access-list” configurations for these two traffic filters

 Use the various “*show isis*” commands to see the IS-IS status of the lab network now. Check the routing and the routing table. If you are missing any adjacencies, work with your neighbouring routers in your AS to work out why, and what might have gone wrong with the neighbour authentication.
-===== Aside: OSPF neighbour authentication =====
+===== Footnote: OSPF neighbour authentication =====
 Neighbour authentication for OSPF is a little more complex than it is for IS-IS. First off, OSPFv2 only supports IPv4 adjacencies and prefixes, while OSPFv3 is used for IPv6.
