BGP Route Annoucement pa MPLS kapena IPSec

Gulu 3: Mbiri Yakale

Mbali Dzina	Kutulutsa Zambiri	Kufotokozera
BGP Route Annoucement pa MPLS kapena IPSec	NFVIS 4.5.1	Mbali imeneyi imakupatsani mwayi sinthani NFVIS kulengeza njira kudzera pa BGP pa MPLS. NFVIS imalola njira zophunziridwa kudzera mu BGP kupezeka pa IPSec panjira yolumikizira MPLS.

• Ndi kukulitsa izi, njira zomwe zidaphunziridwa kudzera mu BGP pa IPSec tunnel tsopano zaloledwa kudzera pa kulumikizana kwa MPLS. Kuphatikiza apo, NFVIS tsopano ikhoza kulengeza njira kudzera mu BGP, pogwiritsa ntchito rauta yomweyo bgp lamulo lomwe limagwiritsidwa ntchito pophunzira njira pa BGP. Kuti mudziwe zambiri pa lamulo ili, onani
• Cisco IOS XE rauta bgp lamulo.
• Mutha kuphatikizira masinthidwe otetezedwa kuti alengeze njira za NFVIS pa BGP kudzera mumsewu wa IPSec.
• Zosintha zomwe zilipo rauta bgp zitha kusinthidwa kuti muwonjezere kulengeza njira. Onetsetsani kuti mwachotsa masinthidwe omwe alipo kale musanayambe kukonza lamulo la router bgp.
