Hi Rene,
Hope you are doing great …
I have some questions …
- What is the advantage Using PHP over Ultimate HOP popping . I am facing some confusion regarding why we will use PHP.
- Suppose 3 ldp Router connected serially … R1+R2+R3 , R1 has a prefix 1.1.1.1 that tag: imp-null and advertise to R2 . R2 also created Tag :16 for 1.1.1.1 and advertise to R1, R3 . Also R3 created Tag:20 for 1.1.1.1 and advertise to R2. So, R2 got those Tags for 1.1.1.1 : 1. Tag :imp-null from R1, 2. Tag: 16 (own creation), 3. Tag:20 from R3 . So my questions is how R2 create LFIB where 3 tags available for same Prefix .
- When PE will receive regular IP packect ,then it will add Label, right ?My questions is why MPLS will kick in . It can forward packet based on IP . What is the lookup process behind this .
