   • BAS path
   • Clocal preference
   • Dweight

   Show answer

   Answer: D

   Explanation

   1. Veryfy that the next hop is reachable 2. Perfer the path with highest weight 3. Prefer the path with highest LOCAL_PREF(100 by default) 4. Prefer the path that was originated locally or through redistribution from an IGP 5. Prefer the path with the smaller AIGP 6. Prefer the path with the shortest AS_PATH 7. Prefer the path with the lowest origin type 8. Prefer the path with the lowest MED 9. Prefer eBGP over iBGP paths 10. Prefer the path with the lowest IGP metric to the BGP next hop 11. Determine if multiple paths require installation in routing table 12. Prefer the path that was received first (Oldest) 13. Prefer the route that comes from the BGP router with the lowest router ID 14. Prefer the path with the minimum cluster list length 15. Prefer the path that comes from the lowest neighbor address

   You are writing an RPL script to accept routes only from certain autonomous systems. Consider this code: RP/0/RP0/CPU0:router(config-rpl)# if as-path in (ios-regex '.*77$') RP/0/RP0/CPU0:router(config-rpl-if)# pass RP/0/RP0/CPU0:router(config-rpl-if)# endif If you apply this code to BGP filters, which effect does the code have on your router?

   • Adenies routes from AS 7070
   • Ballows routes from AS 7077
   • Cdenies routes from AS 7007
   • Dallows routes from AS 770
