Which two statements about SoO checking in EIGRP OTP deployments are true? (Choose two).
A.
During the import process, the SoO value in BGP is checked against the SoO value of the site map.
B.
During the reception of an EIGRP update, the SoO value in the EIGRP update is checked against
the SoO value of the site map on the ingress interface.
C.
At the ingress of the PE/CE link, the SoO in the EIGRP update is checked against the SoO within the
PE/CE routing protocol.
D.
At the egress of the PE/CE link, the SoO is checked against the SoO within the PE/CE routing
protocol.
E.
The SoO is checked at the ingress of the backdoor link.
F.
The SoO is checked at the egress of the backdoor link.
• SoO checking:
– During the import process the SoO value in BGP update is checked against the SoO value of the
site-map attached to VRF interface. The update is propagated to CE only if there is no match (this
check is done regardless of protocol used on PE/CE link).
– At reception of EIGRP update, the SoO value in the EIGRP update is checked against the SoO
value of site-map attached to the incoming interface. This update is accepted only if there is no
match (this check can optionally be done on backdoor router).
