AWK find/replace 2 strings in one shot

Friends,
I have a file with contents like:

interface Serial0/4/0/0/1/1/1/1:0
encapsulation mfr
multilink
group 101
interface Serial0/4/0/0/1/1/1/2:0
encapsulation ppp
multilink
group 101

I just have to repace mfr with ppp and ppp with mfr in a single shot.

I tried using this:
awk '{gsub(/mfr/,"ppp");{gsub(/ppp/,"mfr")}}; 1'

But this 1st replaces mfr with ppp and then ppp with mfr, so finally i get all mfr.

Can somebody help me with this? Can we use SED?
